The Shimano "XTR M9100" BMX Race Disc Brake - Post Mount combines the XTR BL-M9100 lever with its magnesium master cylinder and the two piston BR-M9100 caliper. The lever is 10% stiffer and 26g lighter than the M9000, returns faster and brakes more smoothly, stroke and feedback travel are 30% shorter than on the M9000. The caliper is machined from a cold forged aluminum block and has two ceramic pistons, one way bleeding makes bleeding quick.
It mounts via post mount, the lever clamps to 22.2mm bars via I-Spec EV. The brake is set up for the rear wheel with a right hand lever: the 1700mm SM-BH90-SS hose is fitted to the caliper, the lever is connected by you as a J-Kit, so you can cut the hose to length and route it internally. Only use Shimano mineral oil. Rotor and adapter are not included.
