EXTREME STRENGTH AT NO ADDITIONAL WEIGHT PENALTY.
As experts in designing fatbike components built for extreme conditions, it's no surprise that we were asked to help ebike manufacturers build rear hubs that could survive massive torque while remaining lightweight.
To this end, we designed our No-Nonsense Rear Fatbike around a tooled steel freehub body and a beefed-up star ratchet engagement system.
You've never seen a hub like this before. At 390 grams, our hub is on par with premium lightweight rear fatbike hubs on the market but cuts no corners on freehub durability. Whether you're running a powerful ebike motor, have legs the size of a Kentucky Derby superstar, or need the piece of mind of a component built to last lifetimes, this freehub will show none of the common bite you get from cassettes cutting into most freehubs on the market all while distributing load across an overbuilt engagement mechanism. Better load distribution and more stiffness also means longer bearing life.
WHAT IS A STAR RATCHET HUB?
Used by other quality hub manufacturers like DT Swiss, star ratchet hubs use a combination of springs and teethed rings to create a higher contact ratcheting mechanism that is also significantly lighter than traditional pawl-based freehubs.
Our star ratchet hub is extra burly, distributing torque across 36 deeply grooved points-of-contact opposed to the 4-6 points-of-contact on a pawl-based freehub.
This addresses a common point of failure for many regular hubs where the pawls will break or strip the race in the hubshell causing the power to no longer be transferred to the rear wheel. The even power distribution between the star ratchet teeth ensures a smooth and reliable drivetrain.
NO TOOLS REQUIRED.
The star ratchet hub can be assembled and disassembled with no specialty tools, resulting in easy access to bearings, freehub body replacements, and configuration between 190mm and 197mm frames.
TOOLED STEEL VS EVERYTHING ELSE OUT THERE.
There's no way around it, tooled steel is very heavy stuff. It is also insanely strong, distributes load very effectively, and is very resilient to stripping. By balancing the weight of our rear hub by using star rachet technology we can build a ridiculously strong freehub that holds its own with other premium fatbike hubs on the market.
Our rear hub only comes in a Shimano HG Style freehub body. We chose this freehub body to meet the needs of the largest number of users and drivetrain configurations on the market.

FEEDBACK FROM EBIKE USERS AT BIKTRIX...
I hooked this up to a POWERFUL mid-drive. ZERO issues. Im running a CYC X1 PRO GEN 2 Kit. 72v 5000W. This hub handles it.
I’m in my 5th year riding my Ultra. I have broken my stock hub by overstressing it. Normal pawls-based hubs can’t take my power and the 1,000-watt motors after a few hundred hard climbs. So for peace of mind, I bought the WREN. Now I think it’s unbreakable. If you are a hill climber I think you should consider it.
Great replacement for the OEM hub. Warranty service was excellent
