SRAM R2C TT 10 Speed Time Trial/ Triathlon Shifter Set: These return to centre TT Shifters allow the rider to keep their hands in the most aerodynamic position as the shifter returns automatically to its stating position after each shift. The R2C Shifter can be set up at any angle the rider wishes, be it most aero or most ergonomic, regardless of the angle of the TT Bar extensions. Lance Armstrong has been the prime tester of the R2C Shifters & now they can be seen on Alberto Contadors, Andy & Frank Schlecks & Linus Gerdemanns TT rigs as well as that of the reigning Olympic Time Trial Champion Fabian Cancellara. Ergonomic shifting Carbon shifter blade, titanium bolts Multiple angle setup (40 degree) Will only work with SRAM mechs Weight: 175g
