ATTENTION for FITMENT
SRAM's ULTIMATE brake kits are designed to work with a 2.0 - 2.3mm rotor thickness which comes standard on the R MX4 and X3 concept. These brake kits can be used on the Sur-Ron and MX3 but we recommend switching over to the thicker rotor which will also require 220mm spacers since this brake conversion is going to an oversized rotor.
FRONT Brake Rotors
FRONT and REAR Caliper Spacers
- More caliper stiffness and a new pad compound with bite.
- Pivot bearings for crisp lever feel and a fatigue-free ride.
- SRAM's best power to weight ratio in a four-piston brake.
