Features:Optimized tooth shape for smoother chain installation and shifting process, strong and wear-resistant

3-bolt mounting specification, compatible with 85% of the direct-mount crank specifications on the market, the contact area in the center of the chainring allows for a tighter fit between the chainring and the crank

Optimized tooth shape combined with aluminum alloy 7075 cold forging technology increases the wear resistance of the chainring by up to 50%

The specially shaped teeth play a crucial role in the smoothness of shifting, which helps the chain to be 30% faster in the winding process, resulting in a faster shifting experience

The purpose of the anti-drop chain peg is to prevent the chain from falling outward and then getting stuck in the middle of the crank and chainring, avoiding chain damage due to mechanical problems
