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

There is no quality control. Both front sprockets I received were CRAFTS.

Both chain rings I received from this company were bent. After a month of use, the teeth were completely ground down to a thin razor blade and only on one side. I think at this price there is no room for quality control.

Pros
  • This item 130 Bcd Narrow Wide Single Chainring Black 50T is made of high quality 7075 CNC machined aluminum alloy with anodized finish, light weight, high strength and good performance. Please check the specifications of the 130 BCD crankset carefully before purchasing.
Cons
  • Damaged

Great Product: Drivetrain Components

If you make a 1x setup, you must get this as a buyer, you always want to pay less. But in this case it's very hard to find a 130 BCD installed for less money. Let me tell you this is the best chain that stays in place on an 11 or 40 tooth on a cassette. Yes, there is cross-chain, but it's inevitable.

Pros
  • Multiple Models: Fits CXR Cross/Fixie/Road/MTB/BMX cranksets and compatible with 8/9/10/11 speed chainrings.
Cons
  • Not as thick as other picks
