The R55C4 pads are cartridge-style rim brake pads built by Shimano for road bikes. They’re designed for braking on alloy rims, and fit a broad range of Shimano dual-pivot / direct-mount / caliper-style road brakes — including high-end groups such as Dura-Ace, Ultegra, and 105.
Use Case & Benefits:
Ideal for traditional rim-brake road bikes with caliper brakes.
Predictable stopping power under dry and normal conditions; good modulation and control for road riding.
