Available in 2 choices of compound: Competition cycle disc brake pads Clarks competition cycle disc brake pads are engineered to reduce the build up of heat which directly reduces brake fade, by cleverly increasing the pads surface area. Advanced pad compound comprising of, Kevlar® for high frictional properties, high ceramic content for improved wet weather performance and a increased copper content for superior low speed breaking characteristics, the VRS range of disc pads incorporate all the features required by the serious cyclist in all riding conditions. VRS pads have been developed to provide significant improvements in durability and are CEN, REAch and ROHS compliant. Sintered cycle disc brake pads Clarks sintered cycle disc brake pads use harder compound pad with increased carbon content. Sintered pads are designed to deliver maximum performance under stress and extreme conditions. Consistent through sustained riding they are ideal for hydraulic brake systems Model Compatibility: Avid Elixir 1, 3, 5, 7, Elixir R, Elixir CR SRAM XX, XO Supplied with spring clips where applicable
