|Competition improves the breed: SRAM Red DoubleTap controls break new ground in materials applications and design for even better performance and customized comfort. Driven by the goals of light weight, higher efficiency and advanced materials the DoubleTap is the lightest, most advanced shifter in the world. Internals have been designed for zero-loss shifter travel and a trim feature to optimize front shifting. The ergonomic design factors in comfort and light weight, with a brake and shift lever reach adjuster that allows better comfort and function. Cables can be run one of two ways for maximum compatibility with any handlebar. Compatible with all SRAM 10 speed road drivetrains (must use SRAM front and rear derailleurs). Cables and housings included.
