Electric-assist bikes have unique needs for braking performance. With additional weight and speed from the motor, E-bikes put significant strain on the brake pads. Pro E-Bike disc brake pads are tuned to provide additional stopping power and durabiility. They also offer consistent modulation with little braking noise. WHEN TO USE: Designed for the unique demands of pedal-assist E-bikes, Pro E-Bike pads are perfect for both city E-bikes and E-MTBs.Compatibility: ShimanoXTR M9020, M9000, M987, M985; Deore XT M8100, M8000, M785; SLX M7100, M7000, M675, M666; Deore M6000, M615; Alfine S700; Road/CX RS785, R785, CX77, CX75, R517, R515, R317, R315RidereverCargo-D, ARC- E, ARC-S, ARC-U, Attack-E, Attack-U, MCX-2 (PM), MCX-1 (PM), MTN5Features
