The Shimano R55C4 Cartridge-Type Brake Shoe Set is the easy choice when you want a genuine replacement for Shimano road rim-brake calipers that use this cartridge format. You’re getting 1 pair of complete brake shoes with the R55C4 compound, intended for aluminium rims and officially listed across a broad range of Shimano road and cyclocross calipers, including models in the DURA-ACE, ULTEGRA, 105, Tiagra, Sora, Claris and CX70 families.

On the bike, this pad is best thought of as a dependable OEM-style option: strong dry braking, good wear life, and the familiar Shimano feel that suits everyday road riding, training bikes and straightforward like-for-like servicing. Shimano’s own compatibility charts rate the R55C4 highly for dry power, anti-fade and durability, while wet braking is more moderate than some premium aftermarket compounds. That makes it a smart pick if you want an original-spec replacement that’s easy to match to your Shimano calipers rather than chasing a more aggressive aftermarket feel.

The main thing to get right is compatibility. This is an alloy-rim pad, not the carbon-rim version, and Shimano also gives a 19.6–24 mm rim width recommendation for R55C4. If you’re running older or narrower road rims with Shimano cartridge holders, this is usually the tidy OEM answer. If you’re on very wide rims or specifically want more wet-weather bite, it can be worth looking at alternate compounds in the same Shimano/SRAM-style format.

Ideal for road riders, commuters and workshop builds that need a genuine Shimano cartridge pad for alloy rims and compatible Shimano caliper brakes.
