Powerful SRAM Code R 4-piston hydraulic disc brakes with 203mm rotors offer exceptional stopping power and modulation for confident control in all conditions.

SHMANO SLX/DEORE 1X12 DRIVETRAIN
Equipped with Shimano's SLX shifter and derailleur paired with a durable Deore steel cassette this 1x12-speed drivetrain offers the ideal blend of smooth shifting and long-lasting performance for the rigors of e-MTB riding.
