Shimano 105 ST-R7120 2×12-Speed Shifters

The ST-R7120 Dual Control Levers bring the highly anticipated 12-speed mechanical shifting to the Shimano 105 family. Designed for riders who prioritize the reliability and "fix-it-anywhere" nature of cable-actuated shifting, these shifters pair a refined mechanical internal unit with elite hydraulic disc braking. The R7120 features an updated ergonomic design inherited from the Di2 versions, offering a shorter reach and a more comfortable hood shape that accommodates a wider variety of hand sizes. With a lighter shift action and a more defined "click" than the previous 11-speed generation, these shifters provide a premium tactile experience. Whether you are building a modern endurance machine or an all-weather commuter, the 105 R7120 delivers professional-grade 12-speed performance without the need for batteries.
