EVEN MORE OF A GOOD THING
 
The original Hayduke has been known to get plenty of folks out into the wild. Hayduke LVS is our addition to help get you there with more comfort and more gear. And now, to get you out even further, its available for Fat bike wheels.
 
Staying true to the versatility you have come to know and the durability you have come to depend on, Hayduke LVS can truly do it all and get you even further into the backcountry, and back again on every ride.  
READY FOR THE LONG HAUL
...THE REALLY LONG HAUL
 
The Hayduke LVS FAT is the Hayduke LVS you have come to know, but with more to love. With 600mm chainstays, the LVS gives a smoother ride, more stable handling for really long rides, and more space to carry a lot of gear.
 
All Hayduke LVS FAT frames have external cable routing, threaded bottom brackets, and 44mm head tubes for durability and ease of maintenance.
 
The Hayduke LVS FAT also comes with 30 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.

Pre-Order your Hayduke LVS FAT

You’ve probably seen a few of these around. We made a small prototype run of the Hayduke LVS in Fat Bike form, and have been testing it for a year. By popular demand, we are going to do a limited production run.

Because the Fat Bike market is hard to predict, we will not be regularly stocking this model. We are going to make this one production run on a pre-order only basis.

 

 
To better manage our inventory in the uncertainty of the current global situation, we will be selling all Esker Titanium frames in 2026 on a pre-order basis only, in quarterly batches.  

 
A deposit of $1,000 is placed to secure your frame and production spot. Balance is due when the frame is ready to ship, and forks or complete bike kits can be added at that time

HAYDUKE LVS FAT FAQ

 

  • 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.
    •  

Q - What's the maximum tire width that the Hayduke LVS will take?

  • While the Hayduke LVS FAT was designed around 27.5x4.5" tires, it will fit up to tires labeled 26x5.0" depending on your chainline, rim width, actual tire width, and dropout position.

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

  • The Hayduke LVS FAT is designed around a rigid fork with an Axle to Crown height of 495mm. This is the same as a 120mm travel suspension fork at sag. We also test and approve the use of suspension forks within +/- 10mm of the original 120mm design.

Q - How many water bottles will the Hayduke LVS FAT carry?

  • SM/MD/LG/XL = 2 bottles in the front triangle, 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 FAT also comes with 30 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 single-speed the Hayduke LVS FAT?

  • 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 Hayduke LVS FAT?

  • Technically, yes, but we recommend working with your favorite professional mechanic to figure out which hubs and support parts may be needed. 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 - 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 - What does your warranty look like?

Q - Can I order one of your frames/bikes through a local bike shop?

  • Absolutely. 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 demo a bike before I buy 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.  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.

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 LVS FAT?

  • We don't recommend 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.
  • If you're looking to make a custom bag(s) for your Esker, we've partnered with some incredible custom frame bag makers that all have our frame dimensions and files on hand. Please reach out to one of them HERE.
