Shimano 105 ST-R7120/BR-7170 Hydraulic Disc Shift/Brake (Left, 2-Speed)

The Shimano 105 R7120 Dual Control levers feature a revised lever position and bracket shape developed using data from a broad study of different hand shapes. That’s combined with the all-condition confidence of hydraulic disc brakes and the quick and intuitive shifting cyclists expect from Shimano 105.

Highlighting features:

• Mechanical 12-speed dual control lever with updated ergonomics
• Light shifting operation lets you focus on the road ahead
• New blade shape creates shorter lever access curve allowing riders with a wide range of hand sizes and shapes to comfortably reach their levers
