Shimano Metal Pad Hydraulic IBRM9100MPMX BR-M9100 (K04S)

Hydraulic disc brake calipers from the top-of-the-line "XTR" grade of MTB components. Lightweight 2-piston type for XC racing. Reducing the input force at the fingertips increases braking force and improves linear response. Compared to the previous M9000 model, braking force, stroke, and time lag have been reduced by 30%. Lightweight, highly rigid, one-piece aluminum caliper. ■Suitable for both front and rear.
