The SHIMANO 105 R7120 DUAL CONTROL shift/brake levers feature an improved lever position and clamp shape, based on a comprehensive evaluation of various hand shapes. We combine this with the weather-independent reliability of disc brakes and the quick and intuitive shifting quality familiar from the SHIMANO 105 series. With proven hydraulic brake technology, the new SHIMANO 105 brake calipers impress with the SHIMANO Flatmount system and their optimally flat profile for road bikes. More compact and lighter than ever before, the R7170 brakes provide a wide brake pad clearance, allowing for easy wheel removal, quiet performance, and easy yet thorough maintenance thanks to one-way ventilation.
