*Selecting No BB means no bottom bracket in your order

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

Hollow design, one-piece chainring, different from the traditional square hole center axle, has more stable pedaling rigidity

The non-driven side is the mounting position, using two M6 screws for bilateral locking fixation, with nylon locking screws to achieve the effect of smooth rotation of the chainwheel

Chainring mounting specification is 3-bolt mounting type, supporting the use of power meter

The special tooth angle of the chainring allows for a tighter and smoother fit between the chainring and the chain during the ride
