Updated lever design pivots on ball bearings for smoother shifting action. When things get hectic, a missed shift can be the difference between winning and losing, cleaning a hard section or walking. So SRAM designed the X9 shifters with Exact Actuation for lightning-fast shifts. Crafted from lightweight aluminum and composite materials, the X9s will meet the demands of any rider. You've got plenty to worry about flying down the trail, with SRAM X9 triggers that list gets a lot shorter.
