The GX Eagle chain is designed with SRAM's Eagle geometry, the GX Eagle chain features solid pin construction, Eagle PowerLock and smooth, efficient shifting that you can count on every time out.
All-new Eagle PowerLock chain connector with FLOW LINK technology provides better chain-guiding and increased longevity
Unique features and design also provide significantly improved wear resistance on Eagle cassettes and rings
Based on the DB3 brake design, Level brakes have smaller levers and are lighter. A great choice for all-around mountain biking
The SRAM G2 RS disc brake offers impressive feel and powerful braking performance. SwingLink technology gets brake pads to the rotor fast, then moderates pressure with smooth modulation.
The SRAM GX Eagle DUB Fat Bike crankset delivers consistent performance every time out. Now featuring SRAM's DUB technology, this design simplifies the relationship of the spindle to the bottom bracket. Optimized 7000 series forged aluminum arms support the X-SYNC 2 chainring to provide complete chain control. Now everyone can benefit from a new measure of durability.
SUNRingle Mulefut's are our favorite workhorse fat bike rim. They are tubeless compatible and durable enough for any fat bike adventure. 27.5x65 is the ideal fat bike rim for trail riding. Pair these with the Maxxis Minion 3.8" tires and you have the perfect configuration for all-season use. Compatible with up to 4.5" tires.
Wheelsets include rim strips, rim tape, and tubeless valves.

I absolutely love this bike! The lightweight and superb geometry make it amazing on single track. I don't miss my EMTB at all and I can't wait to ride it this Winter!
Shipping was fast just 2-3 days, everything arrived as expected and in good shape. Assembly was easy after watching the videos a few times, hardest part was seating the tires on the rim (setup with included tubes). I’m new to SRAM so a bit of learning curve threading in the cassette far enough to have sufficient clearance for the highest gear/smallest rear cog)…got it done.
My only concern are the brakes, seems a lot of travel on the levers for new brakes (over an inch or more)…may need to bleed the brakes? I’m contacting support to see next steps.
Wasn't sure what to expect with this being my first fat bike and all but damn I'm impressed. The Crestone feels much lighter than I thought, even with the bigger 120mm fork, and still very planted. The green paint is gorgeous, and the components are top notch. I shopped quite a few other fat bikes and none of them came close in terms of parts spec and craftsmanship for the money. Plus, they're based out of CO and it's always nice to support local! I had a couple last minute add-ons and Steve was quick to reply and get it taken care of before I arrived for pick up. I normally ride a size large gravel bike but I sized down to a medium and it worked perfectly. Can't wait to put many more miles on this thing!
This is my second pair of HED aluminum 26. I have put a lot of trouble free miles on my first set and plan on many more. Thanks to the Borealis team for unparalleled service!!
The Keystone is my first e-bike having been a fat tire mtb enthusiast this was a no brainer, it is the most fun I’ve had on a fat tire bike. Love it !! thanks Borealis.
