Carbon fiber brake lever and dual, internal cable routing for both brake and shifter reduces weight, lightens steering response, and cleans up cockpit aesthetics. Redesigned ergonomics with shimmed reach adjustability and a closer brake pivot point improves braking performance while providing better compatibility with more bar profiles. Compatible with older Ultegra/Ultegra-SL 10-speed shifting systems, but recommended for use with newer 6700 brake calipers. FlightDeck compatibility with access buttons on levers (FlightDeck components not included). Sets include SP41 housing and PTFE-coated cables.
