Zipp Cork composite brake pad inserts Sram/Shimano carbon rims

Zipp Cork composite brake pad inserts Sram/Shimano for carbon rims. Zipp product code: 00.1915.129.010. Designed by Zipp to address the intense heat caused by braking on carbon, it combines the stopping performance and durability of a synthetic polymer with the heat resistance and smooth feel of cork. Composite cork polymer reduces glazing and offers consistent brake response. Avoids the brake pulsation produced by residue buildup from rubber pads; can even eliminate pulsation from rims with previous buildup. Its unique shape places more material in the front of the pad, to improve durability and shed water. May be used on any tubular or clincher rim with a carbon braking surface, but should never be used on aluminum braking surfaces. 8 grams per pair.
