Introducing the new SRAM 1150 R2C Aluminium 11 Speed Shifter Set. Inspired from the SRAM R2C Aero SL-1190 shifter set, the best-in-class Time Trial & Triathlon shifting system used by IM World Champion Pete Jacobs & Mirinda Carfrae, featuring the R2C (Return to Centre) technology at a lower price. No need to bend your hands anymore & benefit from the most aerodynamic position anytime. After every shift it immediately & automatically returns to the starting 'centre'. No more stress, awkward hand positions, or loss of concentration. Just focus on your search for speed. The new SRAM R2C Aero SL-1150 shifting blades are made from lightweight alloy & have an optimized ergonomic shape for comfort & natural handling. Rear shifting is indexed for fast & flawless gear changes, while the front shifter is available for 11 speeds in YAW. R2C function Unlike traditional 'clocking' bar-end shifters, the R2C mechanism returns the shifter blade to its 'home' position after each pull or release stroke. This spring loaded feature allows the rider to maintain the blade & hand position for optimal aerodynamics & concentration. Fit Allowing up to 40 degree blade adjustment, the R2C 'home' position is customize-able to match any rider's fit whether using Straight, Ski-bend or S-shaped bar extensions.
