What to Compare Before Buying
- Brake system: Check that your bike uses a compatible Shimano rim-brake setup from the named range.
- Rim material: These pads are for carbon rims, so compare them with the wheel surface on your bike.
- Exact groupset: Match the listed DURA-ACE, ULTEGRA or 105 version before choosing an offer.
- Pad reference: Confirm R55C4 if you are replacing an existing pad set.
Compatibility, Size and Fit
The main decision point is model compatibility. This pad set is listed for a wide Shimano rim-brake range, but the exact groupset and rim type still need to match. Check both the brake group and the wheel surface on the bike before fitting.
Before You Decide
Confirm the exact Shimano groupset, the R55C4 pad reference and that your wheels use carbon rims. Those are the checks that matter most for choosing the right pad set.
