Engingeered to interface with Bosch motor systems, SRAM drivetrain engineers optimized this ring to combat the high-torque, high-wear situations e-bike riders face. The aggressive T-Type tooth design provides better chain retention for a smoother, more efficient pedal feel with a focus on long wear-life.
