The new X0 2x10 Grip Shifter kit has proven itself on the circuit with a 2011 XC World Champions title. Developed for the BlackBox race program, the first 10-speed Grip Shift shifters were used successfully by Jaroslav Kulhavy.
The X0 uses ball bearings - a first for the Sram grip shifters. This ensures a longer lifespan than a plain bearing, and reduces the effort that's needed to change gears. These shifters use a Sram 1:1 transmission. The 1:1 transmission also facilitates adjustment.
The X0 2x10 Grip shifters are compatible with SRAM 10-speed mountain bike derailleurs and road derailleurs, this opens up opportunities for commuting applications. However, it's only compatible with 2x10 SRAM derailleurs.
