Shimano BR-R451 Caliper Brake, Rear, Silver, Mid Reach, Super SLR, Road

Description:

The Shimano BR-R451 Rear Mid-Reach Road Caliper is designed for riders who need extra clearance for wider tires or fenders without sacrificing braking performance. With a mid-reach range of 47–57mm, it fits a wide variety of road frames. Compatible with Super SLR-enabled STI and brake levers, this caliper delivers light lever action and consistent stopping power.

It features adjustable toe-in cartridge brake shoes for enhanced modulation and reduced brake squeal. For best performance, use with levers that support Super SLR actuation; using standard SLR levers may result in a soft or “mushy� brake feel.

• Light and Responsive Braking: Smooth lever feel and reliable stopping performance.
