Steel crown 38 12 speed black bcd 104mm t-type Sram

Electric bicycles are exposed to high torques, which maximizes wear. To ensure long life, the steel chainring for 1x12 • speed Eagle Transmission systems is dedicated to better control these forces. The Eagle chainring's aggressive T • Type tooth design with 104mm bolt circle diameter (BCD) also improves chain retention, which in turn provides a smoother, more efficient pedaling feel.
