Review on AL7075 1X System: 130 BCD Narrow Wide Single Chainring for CXR Cross/Fixie/Road/MTB/BMX - 8/9/10/11 Speed, 5 Bolt by Mike Travers

Revainrating 5 out of 5

Eliminates ghost trading on e-bikes

I needed a large sprocket for my folding e-bike to help ghost trade. It did the trick and can find pedaling resistance up to 28-29 mph. Good quality and recommended.

Pros
  • Stronger and more durable: 130BCD multifunction prevents the chain from falling off, while the wider tooth design maximizes the ring's durability.
Cons
  • Very expensive
