The SHIMANO 105 R7120 DUAL CONTROL shift/brake levers are characterized by a revised lever position and clamp shape, which is based on a broad evaluation of different hand shapes. We combine this with the weather-independent safety of disc brakes and the fast and intuitive shifting quality you have come to expect from the SHIMANO 105.
With the proven hydraulic brake technology, the new SHIMANO 105 brake calipers impress with the SHIMANO flatmount system and their flat profile, which is ideal for road bikes. More compact and lighter than ever before, the R7170 brakes offer a wide brake pad spacing and thus enable easy removal of the wheels, low-noise performance and, thanks to one-way bleeding, simple and thorough maintenance.
Mechanical DUAL CONTROL shift/brake lever with revised ergonomics
The new shape shortens the access distance to the lever, making it easier to grip comfortably for a wide range of hand sizes and shapes
Easy shifting keeps your concentration on the road
10% greater brake pad spacing reduces the likelihood of rubbing brake rotors
