The Shimano "XTR BR-M9100" BMX Race Brake Caliper - Post Mount is the two piston caliper of the XTR M9100 group. The aluminum body is machined from one block for high stiffness, the pistons are ceramic. According to US Pro it is lighter than the M9000, and stroke and feedback travel are 30% shorter. One way bleeding makes bleeding quick without letting air into the system.
It mounts via post mount, front or rear. The hose connects straight, the matching hose is the SM-BH90-SS. Only the caliper is included, without rotor, hose, lever or adapter. Only Shimano mineral oil belongs in Shimano brakes.
