THE COMPANY

 

Q - Whats an Esker?

  • An esker, eskar, eschar, or os, sometimes called an asar, osar, or serpent kame, is a long, winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America. Eskers are frequently several kilometres long and, because of their uniform shape, look like railway embankments. They happen to make incredible land formations to build singletrack and paths through the wilderness on.

Q - When did Esker start?

  • Thats a bit of a loaded question, but the Esker brand officially kicked off in 2018 when the founder, Tim, set forth to bring Dave Weagle's new Orion Dynamics Suspension platform to market along with the tried and true steel and titanium designs that we've all come to love. An evolution of the brand 'Advocate Cycles', Esker aimed to bring a group of riders and like-minded individuals together to think differently about how build a bike brand that not only focuses on creating the bikes that we all love to ride, but does so in a independed and sustainable way that supports not only the riders using the bikes we create, but the communities and like-minded small businesses that we all want to see grow and flourish in the world of mountain biking.

Q - Where are you located?

  • Another very loaded question! We all joke that we're a bit 'base-less' when it comes to where we're located, but the truth is that our warehouse is located up in Minneapolis, Minnesota where a small portion of our team lives. Most of the Esker crew spends their time traveling, riding, exploring, and taking inspiration from riding regions all around North America (and beyond).

Q - Can I visit the warehouse?

  • Not at the moment. Our warehouse is nothing fancy or special, and we don't have it setup to be viewed/toured by the public. If you order a bike from us a select 'local pickup', theres a good chance we'll let you take a gander around the warehouse and all of the fun things we're working on.

Q - Do you have demo bikes at the warehouse?

  • Yes and No. The demo bikes are on the road traveling around North America the majority of the year. If there is a specific model/size that you're trying to swing a leg over, shoot us an email at info@eskercycles.com and we can double check what we have on hand, or help direct you to one of our amazing retail partners that can work with you to get on a demo locally.
Q - How big is Esker?
 
  • 'Tiny but Mighty' is what we like to say. At the moment, you can count our entire team on one hand...so yeah, pretty small.

ORDERING AND SHIPPING

Q - How does the pre-order process work?
      • A deposit will reserve any incoming frameset or complete. Once your bike is in transit to our warehouse, we will reach out with an update in order to finalize any remaining details of your order. If we miss the initial estimated window by more than 30 days, you can cancel your order for a full refund.  
      • Arrival estimates are included with each pre-order. Estimated dates are based on our incoming inventory timeline, and represent our current best estimate as to when we will receive your bike and begin production.
      • All Esker bikes are proudly assembled to order in the USA. Bike building is a multi-stage process involving many moving parts. Once your bike has arrived, any outstanding details have been finalized, and it has entered into the production stage, we estimate up to 2-3 weeks to build and ship your bike.

Q - How long does it take to get my bike/frame after I order it?

  • That depends. If its a bike/frame that you're placing a Pre Order for, the item will have an ETA window associated with it once you select it on the product page. If its a bike/frame that we have in stock, we will email you the shipping eta once the order is placed - that can vary from 2-6 weeks depending on how many orders are in front of yours.
  • NOTE: If you want to speed up the delivery of your frame/fork, order it through one of our Retail Partners. They receive priority shipping when orders are placed through them.

Q - How much assembly do I need to do if I order the bike directly through Esker?

  • Not much at all. Our complete bikes arrive 90% pre-assembled. For more information and assembly instructions, head on over to our Tech Documents page and click the 'New Bike Assembly Instructions' link.
  • If you would prefer having your bike assembled through your local Esker Retailer, please order your bike directly through them. They'll help you figure out your size, work with you on spec/upgrade options, and get your bike built for you exactly how you want it.

Q - The Size/Color I was looking at is out of stock, is there a way to find the specific combo I'm looking for?

  • Possibly! Shoot us an email at info@eskercycles.com and we'll do our best to connect you with one of our retail partners if they have one in stock.

Q - Do you do custom builds or custom options?

  • We do not. We offer a limited menu of upgrade options for all of our bikes, but we do not do custom builds.
  • If you'd like to have a custom Esker built up, please reach out to one of our Retail Partners and they'll work with you on getting you exactly what you want!

Q - Do you ship overseas?

  • We do! You can check shipping costs by adding the frame/bike that you're interested in to your cart and working through the checkout process.
  • NOTE: Shipping costs do not include any import duties, broker fees, or import taxes.

Q - Can I order a bike/frame through my local bike shop?

  • Absoluetly. That would be the best way to order one of our frames/bikes! Working with your local bike shop allows you to get great insight on which model is right for you, which size may work best for your intended use, and ensure that your bike gets built up and fit to your exact specifications. Jump on over to our Dealer Locator to see a full map of our retail partners and find the one closest to you.

Q - Can I return my bike/frame if it isn't what I want?

 

About Our Bikes

Q - Where are Esker bikes made?
  • Esker works closely with various manufacturing partners overseas to bring our proprietary frames to life. All of our bikes are designed with input from our team located throughout North America and assembled/shipped from our Minneapolis, Minnesota headquarters.

Q - What kind of steel do you use?

  • Our steel framesets utilize a proprietary heat treated 4130 chromoly tubeset that is strong and durable with a fully tuned ride quality specific to each size. We design this tubeset in-house and work with our manufacturing partners to bring it to life. The custom drawn, externally tapered, seamless, quadruplebutted tubeset gives our frames an incredible blend of overall strength while cutting as much weight as possible, yet increasing its torsional rigidity. Did we mention that its size-specific?! So if you ride a Small frame, you won't get the same tubeset as someone who rides a Large. We do this in ensure that riders throughout the size spectrum get the absolute best ride quality that they can.

Q - What kind of Titanium do you use?

  • We build our Titanium frames from seamless, double-butted 3/2.5 Titanium for the utmost in durability. This tubeset provides greater strength to weight ration than any other Titanium frames on the market, and was engineered specifically for this application. Titanium is extremely durable and corrosion-proof, so you can load our frames up with gear, strap on as many bags as you can and ride away knowing that your frame will be able to handle any adventure, through any type of weather...for life!

Q - Do your steel frames ride different than your Titanium frames?

  • Yes and No. Based on our own riding input, as well as a ton of great input and feedback from our customers, find that our steel frames have a very similar feel when it comes to compliance on the trail in comparison with our Titanium frames. The biggest difference that most individuals feel is the weight savings of Titanium. Our Titanium frames are around 650-900grams lighter than their steel counterparts. This weight savings results in a 'snappier' and more 'lively' riding characteristc when on the trail.

Q - What kind of finish do your Titanium frames have? Is there a specific cleaning procedure?

  • Our current Titanium frames utilize a bead-blasted finish that we've found to not only look amazing in person, but still looks amazing after having bags, racks, and bottles strapped to it for months on end. Nothing specific is needed when cleaning this finish, you can use your standard bike-wash and cleaning supplies that you have hanging around the house.

Q - Do I need to 'Frame-Saver' your steel frames after I buy one?

  • NOPE! We treat all of our steel frames with an Electrophoretic Deposition (ED) coating inside and out prior to painting them for rust protection.
 

SIZING AND GEOMETRY

 

Q - What size frame should I buy?
  • See the table below for a complete Esker Cycles model line-up size guide
  • NOTE:  Many folks can fit more than a single frame size. If you find yourself at a height in which you can fit 2 different frame sizes, ask yourself what your riding style is like and where/how you intend to use the bike. A larger frame will feel more stable at high speeds, but not as maneuverable in tighter and more technical situations on the trail. Inversely, a smaller frame will be less stable at speeds, but allow you to pick up and place your wheels in technical sections of trail much easier.

Esker Sizing Chart

Q - Why do you measure your bikes/frames sagged?

  • Thats how you ride them! We're big believers that geometry charts alone don't come close to telling the full story of how a bike is going to feel or ride on the trails, but we do our best to show what those numbers would look like when you're riding the bike...and not when you're leaning it up against a wall.

Q - Can I ride one of your bikes before I purchase it?

  • We do our best to travel around throughout the year and often partner with regional mountain bike festivals or local retail partners to host demos. For the most up to date opportunities, check our Dealer Locator HERE.  You can also see a full map of our retail partners - reach out to them if you're near by and ask them what they may have available for you to demo locally.

 

DEMO OPPORTUNITIES

 

Q - How can I demo an Esker?
  • We do our best to travel around throughout the year and often partner with regional mountain bike festivals or local retail partners to host demos. For the most up to date opportunities, check our Dealer Locator HERE.  You can also see a full map of our retail partners - reach out to them if you're near by and ask them what they may have available for you to demo locally.
 

ORION SUSPENSION

 

Q - What is the Orion Dynamics Suspension platform?
  • The Orion Dynamics suspension platform is a patented suspension design created by Dave Weagle. Esker uses the Orion platform on all of our full suspension bike models.
Q - Does it ride like a DW Link?
  • No. It is a completely new design that happens to be designed by the same person as the DW Link. It is similar in that it is a short dual link design but it differs in that because of being designed around only a single chainring, the various instant centers (pedaling, braking, mass transfer) can be finer tuned to where they need to be. The shock rate is also more linear leading to excellent early bump compliance and mid travel support.
Q - What are some other benefits of Orion?
  • Esker suspension bikes that use the Orion platform are able to offer incredible pedaling efficiency while isolating pedal, suspension, and braking forces. We believe the Orion platform provides an incredible overall ride quality and delivers a more enjoyable experience throughout the entire ride. Check out more information on Orion Suspension HERE
 

SHOCK COMPATABILITY

 

Q - What shocks are used on the Elkat and Rowl?
  • Elkat: Float X 230x60/65- EVOL LV, 0.3 Volume Spacer, CM, RM, Rezi LMB2
    Metric 230x60mm (MW and OG at 150mm rear travel)
    Metric 230x65mm (LT at 162mm rear travel), 8x21mm forward mount, bushing-less clevis rear mount
  • Rowl: Float X 210x55- EVOL LV 0.5 Volume Spacer, CM, RM Rezi LMB2
    Metric 210x55mm, 8x21mm forward mount, bushing-less clevis rear mount

NOTE: an un-tuned shock will not behave as well as the custom tuned shock that is intended to be used on the bike along with the Orion Suspension platform so we do not recommend their use. Shock specs are also listed in the frame specs section of each bike page.

Q - Is the Elkat or Rowl coil shock compatible?

  • As of now, there are no recommended or approved coil shock options.
 

Fork SPEC

Q - What are the recommended fork specs for Hayduke?
  • Hayduke is optimized around suspension forks at 30% sag with an axle to crown height of ~492mm, or a rigid fork with an a-c height of 492mm. For suspension forks, the following are examples of forks that are recommended for use with Hayduke
    • 2023 Hayduke - 29" fork with 120mm travel and 51mm offset
    • 2022 and previous Hayduke - 27.5"+ fork with 130-140mm travel and 42mm-46mm offset or 29" fork with 120mm travel and 51mm offset
    • Rigid fork with an a-c length of 492mm (+/- 5mm) and an offset of 51mm
 
Q - What are the recommended or approved fork specs for Japhy?
  • Japhy is optimized around suspension forks at 30% sag with an axle to crown height of ~492mm, or a rigid fork with an a-c height of 492mm. For suspension forks, the following are examples of forks that are recommended for use with Japhy
    • 29” fork with 120mm travel and 51mm offset (This is the fork spec the Japhy is designed for)
    • 29” fork with 130mm travel and 51mm offset (This fork spec is the maximum allowed, but changes the geometry slightly)
    • Rigid fork with an a-c length of 492mm (+/- 5mm) and an offset of 51mm
 
Q - Can Hayduke or Japhy be set up with a rigid fork?
  • Yes, but it would need to be a "suspension corrected" fork with a similar axle to crown height as outlined in the Geo charts
Q - What are the recommended fork specs for Elkat?
  • Elkat is optimized around a 27.5" 160mm suspension fork with a 44mm offset and can be used with up to a 170mm fork.
Q - What are the recommended fork specs for Rowl?
  • Rowl is optimized around a 29" 150mm suspension fork with a 44mm offset and can be used with up to a 160mm fork.

NOTE: Fork offsets have been a topic of discussion for quite some time in the mountain bike community. There are pros and cons to both short and long offset options. While we may have originally designed our frames around either a short or long offset fork, we've spent a lot of time expirimenting and riding both options and are quite happy with the results of either short offset forks, or long offset forks. Much of it comes down to personal preference, your own riding style, and what type of trails/terrain you're riding on. Feel like expirimenting with an offset that your Esker wasn't originally designed around? Have at it! Bikes are supposed to be fun and unique expressions of the individual riding them...don't sweat the details too much.

  • Classic Portage Quick Release: *no longer produced*
    • Advocate Cycles Lorax Only - 142mm Quick Release.
  • 142mm Single Speed: *no longer produced*
    • Hayduke and Japhy (Steel and Titanium)
  • 142mm Fixed Position Geared: *no longer produced*
    • Hayduke and Japhy (Steel and Titanium)
  • Classic Portage Adjustable:
    • Esker Cycles Lorax Titanium: 142mm spacing // 167mm axle // M12x1.75 thread pitch.
    • Hayduke and Japhy (Steel and Titanium): 148mm spacing // 174mm axle // M12x1.75 thread pitch.
    • Esker Cycles Walden Titanium: 197mm spacing // 229mm axle // M12x1.75 thread pitch.
  • UDH Fixed Position: 
    • Hayduke and Japhy (Steel and Titanium): 148mm spacing // 180mm axle // M12x1.0 thread pitch.
  • UDH Adjustable:  
    • Hayduke and Japhy (Steel and Titanium): 148mm spacing // 180mm axle // M12x1.0 thread pitch.

Q - What hardware works with each portage dropout?

  • Classic Portage QR: M8x14mm stainless bolts x4 // M8 stainless nuts x4
  • Classic Portage Adjustable:
    • Geared: M8x14mm stainless bolts x4 // M8 stainless nuts x2 // Fixed Adjustable Nut x2
    • Single Speed // Adjustable: M8x14mm stainless bolts x4 // M8 stainless nuts x4 // M3 set screws x2
  • UDH Fixed Position: M8x14mm stainless bolts x4 // M8 stainless nuts x4 // applicable UDH
  • UDH Adjustable: M8x14mm stainless bolts x4 // M8 stainless nuts x4 // M3 set screws x2 // applicable UDH
Q - Why does Fixed Position UDH dropout exist if the Adjustable Position dropout can be run geared?
  • The Fixed Position UDH dropout was designed to be allow for the absolute shortest chainstay length possible with a UDH. As a result, it only adds 5mm to your frame's shortest advertised position (original chainstay lengths were measured with the 'Classic Portage' dropouts.

Q - Can I adjust my chainstay length with a Portage Dropout?

  • Absolutely! If you're looking to run your Portage Dropout equipped frame as a single speed, want to extend your chainstay for more tire clearance, or simply want to play around with different handling characteristics, the Portage Dropout system will allow you to adjust your chainstay length up to 14mm. (Measurements are taken from the shortest advertised chainstay length for each model)
    • Classic Adjustable Portage Dropouts:  Using the FAN System
      • Position 1: +0mm
      • Position 2: +3mm
      • Position 3: +6mm
      • Position 4: +14mm
    • UDH Adjustable Portage Dropouts:  Using the FAN System
      • Position 1: +7mm
      • Position 2: +10mm
      • Position 3: +13mm
      • Position 4: +21mm

Q - How does the Fixed Adjustable Nut (FAN) work?

  • The FAN allows for chainstay length adjustment without using set screws, and gives a more durable attachment than nuts used for a sliding mode. FANs work with both Classic and UDH Adjustable Portage Dropouts. The 2 threaded holes in the FAN allow for 4 unique dropout positions/chainstay lengths. See the image HERE for more details.
Q - Can Hayduke/Japhy be run as a Single Speed?
  • Yes, our Portage Dropout System allows for 14mm of horizontal adjustment allowing you to set it up as a dedicated single speed or convert it to single speed in an emergency trailside situation. If your current Portage Dropout uses a FAN, you'll want to replace it with an M8 Nut.

Q - What are the torque specs for the Portage Dropouts?

  • M8 Bolts = 12nm // Axle = 9-12nm`

Q - How do the Portage Dropout Rack Mount Bolts work?

  • Rack Mount Bolts allow the addition of a rear rack to any Esker bike using the Portage Dropout system. Additional threads within the extension bolt allow racks to be mounted to the bolts from the outer side. Rack Mount bolts act as a stand-off from the frame for mounting a rear rack. They are broached for 8mm Allen just like the standard hardware, but are also center tapped for M5 (standard rack size). These are to be specifically utilized on Esker hardtails that do not have existing rack mounts, or if you’d prefer a lower mounting solution than what the frame mounted rack mounts provide.  

Q - How do the Portage Dropouts effect tire clearance?

  • The adjustability that Portage Dropouts can allow will help to increase the overall tire clearance as you extend the overall chainstay length. For example: The Hayduke Steel has clearance for a 29x2.5" tire in the 423mm chainstay position, and 29x2.8" clearance in the 437mm chainstay length position using the Classic Portage Dropouts.

Maximum Tire Size

 

Q - What are the maximum tire clearances for your frames?
  • Elkat: 27.5x2.6"
  • Rowl: 29x2.5"
  • Hayduke/Hayduke Ti: 29x2.5" in the 423mm Chainstay Length position, and 29x2.8" or 27.5x3.0 in the 437+mm Chainstay Length positions.
  • Japhy/Japhy Ti: 29x2.5" in the 423mm Chainstay Length position , and 29x2.8" in the 437+mm Chainstay Length positions.
  • Hayduke LVS: 29x2.8" tires if you're running it with gears, and 29x3.0" tires if you run it as a single speed. The chainline interfering with the tire is the primary limiting factor when running the LVS with gears.

NOTE: Tire widths can vary between manufactures. Both tire width and rim width will play a role when figuring out clearnaces. The best way to see if the specific tire/rim combination is going to work with your frame will be to test-fit the wheel in the frame with your preferred tire installed.

*For even more information on how chainstay the Portage Dropout System can effect tire clearance, scroll to the Portage Dropout section of the FAQ*

HUB Spacing

 

Q - What hub spacing is used on Esker bikes?
  • Currently, all of our mountain bikes are designed around the Boost standard of 148mm rear hub spacing and 110mm front hub spacing.
Q - Can I purchase a Hayduke/Japhy with 142mm dropouts instead of 148mm?
  • Unfortunately not, we no longer manufacture the older 142mm spacing Portage Dropouts. Maybe its time for that wheel upgrade you've been holding off on? :)

 

Chainline

 

Q - What chainline are Esker bikes designed around?
      • All of our mountain bikes are designed around the Boost 148mm rear spacing standard, and a 52mm chainline for mechanical drivetrains, or 55mm chainline when using SRAM's Transmission.

 

Maximum CHAINRING SIZE

Q - What is the maximum chainring size that I can install on my Esker?
  • All of our hardtail mountain bikes are designed with clearance for a 34t round chainring or 32t oval chainring.
  • Our Full Suspension Bikes are designed with clearance for a 32t round chainring or 30t oval chainring.

BRAKE MOUNTS / ROTOR SIZE

Q - What disc brake adapters do I need?
  • Our hardtail mountain bikes utilize our modular Portage Dropout System.
    • The Classic Dropout uses IS mounts designed around a 160mm native rotor size. You will need to use a 0mm IS disc brake adapter when using a 160mm rotor, and a 20mm IS disc brake adapter when using a 180mm rotor.
      • 160mm Shimano rotor: SM-MA-F160P/S or SM-MA-R140P/S
      • 160mm SRAM rotor: 0mm IS disc brake adapter
      • 180mm Shimano rotor: SM-MA-F180P/S or SM-MA-R160P/S
      • 180mm SRAM rotor: 20mm IS disc brake adapter
      • 203mm Shimano rotor: SM-MA-F203P/S or SM-MA-R180P/S
      • 200mm SRAM rotor: 0mm IS disc brake adapter
    • The UDH Dropout (Fixed or Adjustable) uses post-mounts designed around a 180mm native rotor size.
      • 180mm Shimano rotor: No adapter needed
      • 180mm SRAM rotor: No adapter needed
      • 203mm Shimano rotor: SM-MA-F203P/PM
      • 200mm SRAM rotor: 20mm PM disc brake adapter
Q - What disc brake adapters do I need for my Elkat/Rowl?
  • The Elkat and Rowl use post mounts designed around a 160mm native rotor size, and can clear up to a 203mm rotor.
    • 160mm Shimano rotor: No adapter needed
    • 160mm SRAM rotor: No adapter needed
    • 180mm Shimano rotor: SM-MA-F180P/P2
    • 180mm SRAM rotor: 20mm PM disc brake adapter
    • 203mm Shimano rotor: SM-MA-F203P/P2
    • 200mm SRAM rotor: 40mm PM disc brake adapter

Rack Information

Q - How do I install the Molle Rackwald on my Hayduke LVS?

  1. Bolt the Molle Boards to the Rear Frame Mounts. Keep slightly loose on both sides (1-2 threads showing).
  2. Install Struts (8020 extrusions) to connect both Molle Boards. These can be placed in whatever location suits your cargo carrying needs best - Keep slightly loose on both sides (1-2 threads showing).
  3. Flex Molle Boards to align with the Forward Frame Mounts - Keep slightly loose on both sides (1-2 threads showing)
  4. Gradually tighten all bolts 1/2-1 full turn until all bolts are tight.  
  5. Load up your Molle Rackwald and escape into the Wild!
Q - I have an Esker hardtail that doesn't have rear rack mounts on the frame, how do I install a rear rack?
  • You'll need a part of Portage Rack Mount Bolts and a seat collar with the ability to attach a rack to it. The Portage Rack Mount Bolts will replace the top M8 hardward on your Portage Dropout and allow you to thread in an M5 bolt to help you attach a rear rack.
  • This hardware can also be utilized on our hardtails that already have rear rack mounts if you wanted place your rear rack struts further back and lower on the frame.

 

HAYDUKE LVS FAQS

Looking for a review?

    • Check out this incredible review from The Radavist - CLICK HERE
    • Or this great video from Hardtail Party - CLICK HERE
  • Q - What size frame should I buy?
    • See the table below for a complete Esker Cycles model line-up size guide. The Hayduke LVS uses the identical measurements and angles as our beloved Hayduke and therefore the same size guide.
  • NOTE: Many folks can fit more than a single frame size. If you find yourself at a height in which you can fit 2 different frame sizes, ask yourself what your riding style is like and where/how you intend to use the bike. A larger frame will feel more stable at high speeds, but not as manuverable in tighter and more technical situations on the trail. Inversly, a smaller frame will be less stable at speeds, but allow you to pick up and place your wheels in technical sections of trail much easier.

Esker Sizing Chart

Q - What wheel sizes can I use on the Hayduke LVS?

  • The Hayduke was designed and optimized for 29" wheels (up to a 2.8" width).

Q - I really want to run a 29x3.0 tire on the Hayduke LVS, why can't I?

  • Bikes are a lot of fun to play with, and we won't tell you what to do or not to do with them, but our official stance on a 29x3.0 tire is 'No'. Yes, the frame clears 29x3.0 tires, but chain clearance and drivetrain are the limitations.

Q - What fork travel can I use on the Hayduke LVS?

  • The Hayduke is designed around 120mm suspension forks (30% sag with an axle to crown height of ~495mm, or a rigid fork with an a-c height of 495mm). We also test and approve the use of 130mm forks on the Hayduke as well.
  • NOTE: Fork offsets have been a topic of discussion for quite some time in the mountain bike community. There are pros and cons to both short and long offset options. While we may have originally designed our frames around either a short or long offset fork, we've spent a lot of time experimenting and riding both options and are quite happy with the results of either short offset forks, or long offset forks. Much of it comes down to personal preference, your own riding style, and what type of trails/terrain you're riding on. Feel like experimenting with an offset that your Esker wasn't originally designed around? Have at it! Bikes are supposed to be fun and unique expressions of the individual riding them...don't sweat the details too much.

Q - Can I run a rigid fork on the Hayduke LVS?

  • Absolutely! Rigid works with an axle to crown measurement of ~492mm work best to maintain the original geometry design and ride characteristics.

Q - What length dropper comes with a complete build?

  • SM = 150mm PNW Loam dropper that can be adjusted down to 125mm of travel, or a 160mm Wolf Tooth Dropper that can be adjusted down to 110mm of travel.
  • MD/LG/XL = 170mm PNW Loam dropper that can be adjusted down to 145mm of travel, or a 200mm Wolf Tooth Dropper that can be adjusted down to 150mm of travel.
    • For more information on the adjustability of the PNW Loam dropper, click HERE.
    • For more information on the adjustability of the Wolf Tooth dropper, click HERE.

Q - How many water bottle mounts does the Hayduke LVS have?

  • SM = 1 bottle in the front traingle, 1 bottle under the down tube
  • MD/LG/XL/XXL = 2 bottles in the front traingle, 1 bottle under the down tube

Q - How many mounting points on the frame are there for bottles, bags, racks, and other gear?

  • The Hayduke LVS also comes with 26 attachment points for adventure accessories, and M6 threaded rack mounts built into the frame for the attachment of Molle Rackwald, our proprietary direct-fit rack.

Q - Can I put a rear rack on the Hayduke LVS?

  • Heck yeah! 2023+ frames have integrated rear rack mounts on the seatstay for using our proprietary direct-fit Molle Rackwald, or many other rear rack options on the market.

Q - Can I single-speed the Hayduke LVS?

  • You betcha! Our Portage Dropout System allows you to adjust the chainstay length by up to 14mm, allowing you to run a single speed setup reliably, quietly, and with ease. Heck, we even have a single speed build option that you can buy!

Q - Can I run an internally geared hub on the Hayduyke LVS?

  • Technically, yes, but we don't offer any support on figuring out which hubs and support parts may be needed in order to make this happen. Have fun!

Q - How does the Portage Dropout System work?

  • The Portage Dropout System attaches to our hardtail frames and allows you to adjust chainstay length (for ride characteristics or tire width clearances), chain tension (for single speed application), or different hanger types (UDH or Classic).

Q - How long does it take to get my bike/frame once I order it?

  • That depends. If its a bike/frame that you're placing a Pre Order for, the item will have an ETA window associated with it once you select it on the product page. If its a bike/frame that we have in stock, we will email you the shipping eta once the order is placed - that can vary from 2-6 weeks depending on how many orders are in front of yours.
  • NOTE: If you want to speed up the delivery of your frame/fork, order it through one of our Retail Partners. They receive priority shipping when orders are placed through them.

Q - How much assembly do I need to do if I order a bike directly through the webstore?

  • Not much at all. Our complete bikes arrive 90% pre-assembled. For more information and assembly instructions, head on over to our Tech Documents page and click the 'New Bike Assembly Instructions' link.

HAYDUKE FAQS

  • Looking for a review?
    • Check out this recent review from Bikepacking.com - CLICK HERE
  • Q - What size frame should I buy?
  • See the table below for a complete Esker Cycles model line-up size guide
  • NOTE: Many folks can fit more than a single frame size. If you find yourself at a height in which you can fit 2 different frame sizes, ask yourself what your riding style is like and where/how you intend to use the bike. A larger frame will feel more stable at high speeds, but not as maneuverable in tighter and more technical situations on the trail. Inversely, a smaller frame will be less stable at speeds, but allow you to pick up and place your wheels in technical sections of trail much easier.

Esker Sizing Chart

Q - What wheel sizes can I use on the Hayduke?

  • The Hayduke was designed and optimized for 29" wheels (up to a 2.8" width). However, the rear triangle will clear a 27.5x3.0" tire if you would prefer running a '27+' setup.
  • NOTE: Models of the Hayduke prior to 2023 were designed and optimized around 27.5x2.8" wheels/tires. If you have one of these frames and want to run 29" wheels, a 29x2.4" wheel/tire combination will work as well.

Q - Whats the maximum tire width that the Hayduke will take?

  • 29x2.5" in the shortest chainstay length position, and 29x2.8" or 27.5x3.0" in the furthest back chainstay length position.

Q - What fork travel can I use on the Hayduke?

  • The Hayduke is designed around 120mm suspension forks (30% sag with an axle to crown height of ~495mm, or a rigid fork with an a-c height of 495mm). We also test and approve the use of 130mm forks on the Hayduke as well.
  • NOTE: Fork offsets have been a topic of discussion for quite some time in the mountain bike community. There are pros and cons to both short and long offset options. While we may have originally designed our frames around either a short or long offset fork, we've spent a lot of time experimenting and riding both options and are quite happy with the results of either short offset forks, or long offset forks. Much of it comes down to personal preference, your own riding style, and what type of trails/terrain you're riding on. Feel like experimenting with an offset that your Esker wasn't originally designed around? Have at it! Bikes are supposed to be fun and unique expressions of the individual riding them...don't sweat the details too much.

Q - Can I run a rigid fork on the Hayduke?

  • Absolutely! Rigid works with an axle to crown measurement of ~492mm work best to maintain the original geometry design and ride characteristics.

Q - What length dropper comes with a complete build?

  • XS/SM = 150mm PNW Loam dropper that can be adjusted down to 125mm of travel, or a 160mm Wolf Tooth Dropper that can be adjusted down to 110mm of travel.
  • MD/LG/XL/XXL = 170mm PNW Loam dropper that can be adjusted down to 145mm of travel, or a 200mm Wolf Tooth Dropper that can be adjusted down to 150mm of travel.
    • For more information on the adjustability of the PNW Loam dropper, click HERE.
    • For more information on the adjustability of the Wolf Tooth dropper, click HERE.

Q - How many water bottles will the Hayduke carry?

  • XS/SM = 1 bottle in the front traingle, 1 bottle under the down tube
  • MD/LG/XL/XXL = 2 bottles in the front traingle, 1 bottle under the down tube

Q - Can I put a rear rack on the Hayduke?

Q - Can I single-speed the Hayduke?

  • You betcha! Our Portage Dropout System allows you to adjust the chainstay length by up to 14mm, allowing you to run a single speed setup reliably, quietly, and with ease. Heck, we even have a single speed build option that you can buy!

Q - Can I run an internally geared hub on the Hayduyke?

  • Technically, yes, but we don't offer any support on figuring out which hubs and support parts may be needed in order to make this happen. Have fun!

Q - How does the Portage Dropout System work?

  • The Portage Dropout System attaches to our hardtail frames and allows you to adjust chainstay length (for ride characteristics or tire width clearances), chain tension (for single speed application), or different hanger types (UDH or Classic).

Q - The Size/Color that I want is out of stock, is there anyway to get the specific one I want?

  • Possibly! Shoot us an email at info@eskercycles.com and we'll do our best to connect you with one of our retail partners if they have one in stock.

Q - How long does it take to get my bike/frame once I order it?

  • That depends. If its a bike/frame that you're placing a Pre Order for, the item will have an ETA window associated with it once you select it on the product page. If its a bike/frame that we have in stock, we will email you the shipping eta once the order is placed - that can vary from 2-6 weeks depending on how many orders are in front of yours.
  • NOTE: If you want to speed up the delivery of your frame/fork, order it through one of our Retail Partners. They receive priority shipping when orders are placed through them.

Q - How much assembly do I need to do if I order a bike directly through the webstore?

  • If you'd like to have a custom Esker built up, please reach out to one of our Retail Partners and they'll work with you on getting you exactly what you want!

Q - What kind of steel do you use?

  • Our steel frames utilize an in-house designed proprietary 4130 chromoly tubeset. This custom drawn, externally tapered, seamless tubeset is quadruple butted to ensure the best combination of weight savings, torsional rigidity, and overall strenght. We heat treat all of our steel frames and finish them off with an electrophoretic deposition (ED) coating inside and out prior to paint. This ED coating helps to protect the frame from rust and corrosion (no frame saver needed!)

Q - What kind of Titanium do you use?

  • We build our titanium frames from seamless, double-butted 3/2.5 titanium. This tubeset provides an incredible balance of weight and strength that we find to be paramount for those big backcountry missions and covering the countless miles of abuse we've seen on our frames. We engineer this tubing specifically for this application and value Titanium's longevity both in fatigue, abrasion and corrosion resistance.

Q - Do your steel frames ride different than your Titanium frames?

  • Yes and No. Based on our own riding input, as well as a ton of great input and feedback from our customers, find that our steel frames have a very similar feel when it comes to compliance on the trail in comparison with our Titanium frames. The biggest difference that most individuals feel is the weight savings of Titanium. Our Titanium frames are around 650-900grams lighter than their steel counterparts. This weight savings results in a 'snappier' and more 'lively' riding characteristc when on the trail.

Q - Do I need to 'Frame-Saver' your steel frames after I buy one?

  • NOPE! We treat all of our steel frames with an Electrophoretic Deposition (ED) coating inside and out prior to painting them for rust protection.

Q - What does your warranty look like?

Q - Should I get a Hayduke or a Japhy?

  • How do you ride?
    • The Japhy is an everything trail bike - its your night ride bike, its your durable hardtail, and it can even do an overnighter once in while. The geometry is designed to be a bit more stable at high speeds, wheelie and bunnyhop easier, and lower your center of gravity by not only using a smaller front triangle and lower standover height, but a lower bottom bracket to get your feet a little closer to the ground. It also has a steeper seat tube angle than the Hayduke, making it much more enjoyable for seated climbs, and a little less forgiving on flatter, more pedaling based rides.
    • The Hayduke is a more dedicated bikepacking bike made to take more gear. It has more front triangle space, more neutral geometry for hauling a load, and more places to mount gear. It also has a more relaxed seat tube angle than the Japhy, which makes it more comfortable for flatter, more pedaling based rides.
      • If you carry gear 10% of the time, and mostly just want an awesome riding hardtail that you can depend on, get the Japhy. If you carry gear more than 50% of the time, and wanted a more dedicated bike for that purpose, get the Hayduke.

Q - I want to buy a frame bag before my bike/frame arrives to me, can you provide the frame bag dimensions for the Hayduke?

  • We don't recommed buying a frame bag until you have your frame/bike on hand. That is absolute best way to ensure you get the right size and shape for your bike.
