A million miles away from the previous avid offerings in terms of reliability.

SRAM Guide RSC brakes feature an all-new design, alleviating the bleeding and consistency woes of the predecessor Elixir product line. Featuring fully adjustable lever position and pad actuation, Guide RSC offers on-the-fly settings for even the most particular rider. A new SwingLink cam design delivers quicker lever take up with improved power modulation before rotor lockup. The new Centerline rotor is stronger with better heat resistance, also eliminating the dreaded warble noise associated with Avid brakes of old. And the integrated MatchMaker system enables all SRAM and RockShox cockpit controls to be mounted with just two clamps. Shimano should be nervous — SRAM Guide RSC brakes are every bit as good, and in some ways better, than the beloved XT and XTR brake lines.
