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 X-9 shifters with Zero Loss technology for lightning-fast shifts. Crafted from lightweight aluminum and composite materials, the X-9s will meet the demands of any rider. You've got plenty to worry about flying down the trail. With SRAM X-9 triggers, that list gets a lot shorter.
