Review on 🚲 KCNC Road Cyclocross Gravel E-Bike Bicycle Rear Derailleur OSPW System Cage for Sram Red/Force/Rival Mechanical 10/11 Speed by Maurice Branch

Revainrating 5 out of 5

LOVE OS derailleurs, but Sram is struggling!

Good pulley system. I can no longer hear my chain. The only problem was the installation. Said it wouldn't work on the Sram Apex system... but it actually works. Sram made the pickup body about .0001" longer than the Rival or Reds body, meaning you won't be able to install the locking pin. To fix this I took a random orbital sander and sanded down the body as thick as a human hair (yes let Sham resize by thousands of inches so people can't attach add-ons like this...seriously shame? ). Needless to say, the installation was quite a hassle. But it had nothing to do with this product. After I modified the Sram Apex body it fit perfectly. No questions. Runs very smooth and quiet.

Pros
  • WHY USE A RAISED PULLEY WHEEL CAGE - Upgrade your drivetrain for maximum efficiency and superior performance. KCNC wheel bearings reduce friction, which reduces rolling resistance. Replacing your wheel bearings with an oversized pulley will maximize your energy return.
Cons
  • Slightly dented
