Review on Enhance Bike Stability with Grin Technologies FRONT Torque Arm: Fork-mounted Solution with Fender Eyelet Compatibility and Robust Stainless Steel Plate by Chucky Hepler

Revainrating 5 out of 5

Perfect fit for Surly Karate Monkey forks!

I agree with all the other reviews on here about the excellent quality of this product. Thick steel, good fit gives me confidence when running a 1000w front hub motor (boosted to 30 amps and peaks at 1500w). The only thing I can add to these reviews is that it works great with the Surly Karate Monkey fork and fits perfectly on the fender loop. The only thing I need to change is to file the C-disk a bit to match the attorney's lips. I used to use the cheaper torsion arms that are sold and was very disappointed when they twisted on the cheaper steel fork and destroyed it. But Surly definitely fits and I have this fork on another e-bike.

Pros
  • Great for me
Cons
  • Easily repairable
