Resin Vs Metal
Compared to metal pads, the resin compound is quiet, generates less heat, and offers more progressive stopping power (no sudden braking). The only compromise? Resin has a shorter lifespan than metal, especially under wet conditions.
Note: Updated with a new resin compound, the B03S lasts up to 40% longer than the previous generation (B01S).
