Shimano BR-RS805/RS505 Flat Mount (K02S) Resin Disc Brake Pad

It's OK for your legs to fade at the top of a long climb -- after all, you've got the descent to recover. When it's your brake pads fading between switchbacks at high speeds, though, it can result in an over-the-guardrail disaster. Replacing your road disc brake's pads with Shimano's BR-RS805/RS505 Flat Mount K02S Resin Disc Brake Pad helps reduce the risk of inconsistent, noisy brakes that gradually fade during heavy use. Since they're resin instead of metal, the pads also provide a much wider range of stopping power, so you can modulate effectively on those long descents but still throw the emergency brake when necessary.
