Shimano BR-R451 Mid-Reach Road Bike Brake Caliper

Shimano BR-R451 Front Road Brake Caliper: Precision Stopping Power for Your Road Bike

Experience confident descents and precise speed control with the Shimano BR-R451 front brake caliper. Engineered for road cyclists demanding reliable performance, these mid-reach calipers (47-57mm) deliver exceptional modulation and powerful stopping force when paired correctly.

Key Advantages for Road Riders:

• Super SLR Optimized: Achieve crisp, immediate braking response only when used with compatible Super SLR-enabled STI levers (e.g., Dura-Ace Di2 7970/7900, Ultegra Di2 6770/6700, 105 5700, Tiagra 4600). Avoid a “mushy” feel by ensuring correct lever compatibility – this caliper requires Short Pull Super SLR actuation.
• Light Action & Control: Enjoy effortless lever feel without sacrificing power. The refined mechanism provides excellent feedback for smooth speed modulation during fast group rides or technical descents.
• Precision Adjustability: Fine-tune pad contact using the integrated adjustable toe-in feature. This minimizes noise and ensures even pad wear for consistent braking performance mile after mile.
• Easy Maintenance: Featuring cartridge-style brake pads, swapping worn pads is quick and tool-free, minimizing downtime and keeping you on the road.

Perfect Fit & Performance:

Designed specifically as a front brake caliper in sleek black, the BR-R451 integrates seamlessly into high-performance road setups where predictable braking is non-negotiable. Its mid-reach design accommodates a wider range of road frames and fork clearances.
