XTR BR-M975 Hydraulic Brake Caliper

The XTR hydraulic brake caliper has undergone a number of refinements. The basic design, one-piece forged-aluminum caliper with two pistons, remains the same, but weight has been reduced by 33g for the set and oil volume increased for greater stopping power. The look has been updated to match the rest of the XTR 970 line as well.

The BR-M975 XTR Disc Brake Caliper comes in two styles, one mounts on International Standard mounts (BR-M975), the other, the BR-M975P mounts on post-type mounts. They’re compatible with both the ST-M975 XTR Dual Control Levers and BL-M975 XTR brake levers. The brakes are hydraulic and run on Shimano Genuine Mineral oil. The design is an opposed two-piston mount. The calipers are made of aluminum and anodized.

Please note: almost all hydraulic brake lines need to be cut to size before a bike is properly shod with hydraulic disc brakes. You'll need a quality cable-cutter like the Park CN-10 and a spoke inserted in the end of the line to first cut and then de-crimp the housing.

The M975 (caliper only) weighs in at 94g. Rotors and levers purchased separately.
