Zipp Tangente Platinum Pro Evo Brake Pad Zipp redesigned their Tangente brake pads featuring a slimmer design that increases pda life and radiates heat over a larger area of the rim for lower peak temperatures. A new groove design has two functions. First, the design offers improved cooling by channeling air over the rim and imrpoved wet weather performance by functioning as a drain to bring water away from your rims and braking surface. A 10 percent increase in surface area than the previous pad model for greater max braking power. A 1 mm thinner design provides improved clearance with integrated brakes. Despite a reduced thickness, its increased radial height increases pad life. Increased radial height also spreads heat over larger "swept area" of the rim for lower peak temperatures. New groove design sweeps water off rim for improved wet-weather braking performance and also channels air over rim to improve cooling. Uniquely formulated compound manages the extreme temperatures that can result from heavy braking on carbon. | Zipp | Tangente | Platinum | Pro Evo Brake Pad Pair - Shimano/sram, For Carbon Rims
