The ultimate goal while on the trail is to minimize the need for frequent shifting. The ADVENT X Trail Trigger Pro from microSHIFT boasts precise ergonomics that place the shift levers in the optimal position for quick thumb access without compromising grip, even on rough terrain. With smooth lever action and precise indexing, you'll never miss a shift. The lower lever also features an integrated silicon traction pad for improved thumb grip. For optimal performance, this shifter is only compatible with microSHIFT ADVENT X 10-speed drivetrains and is not compatible with Shimano or SRAM systems.
