The Shimano BR-M4100 Disc Brake system equips your 10-speed Deore group with the I-SPEC EV clamp, short-stroke lever, and a powerful two-piston caliper with responsive engagement. The short-stroke lever actuation engages the rotor with limited lever-pull, leaving much more range to apply the pressure you need for the specific braking conditions in which you’re riding. I-SPEC EV clamp creates a cleaner cockpit area, affords higher levels of tunabilty, and provides an additional contact point on the bars for more stable lever pull in high-pressure braking conditions. The quick install and ease of set up gets you on the trails in no time.
