With a potent mix of high-grade materials, including a forged aluminum body, titanium spring, and reinforced carbon composite pulley cages, the Sram X0 is a pro-ready, 10-speed rear derailleur that's lighter, stiffer, smoother and flat-out better looking than anything out there. Compatible with Sram 1:1 shifters.
