Description One caliper design is used for both front and rear applications. Compatible with 160mm and 140mm rotors For front brakes the same caliper adaptor is used for 160mm and 140mm rotor applications. Just rotate the included adaptor 180 degrees to switch between the two sizes Rear brakes are natively 140mm rotor compatible and can be adapted to 160mm rotors with an included caliper spacer SRAM recommends 160mm rotors front and rear for ideal braking power, modulation and heat dissipation
