SHIMANO Dura Ace Di2 ST-R9170 Gear/Brake Lever Right for Disc Brake Black 2017 Gear Lever

Dura-Ace Di2 STI's high-performance hydraulic disc brake gives you control, modulation and performance with minimal effort in all riding conditions. With Di2 technology, shifting is easy and precise - just a light touch, as soft as a mouse click, is enough for the front or rear derailleur to immediately select the right gear. Removing traditional mechanical cables in favor of electrical wires prevents bad shifting due to impurities, corrosion and stretching and also provides effortless gear shifting. Simply pressing push buttons allows for effortless and comfortable shifting when your hands are cold. Shifters are thanks thanks to Carbon fiber, the retainer body made of carbon composite and a titanium clamp/fastening bolt Drop Bar STI with shift knobs located in a nearly identical location to the positions you would move with a mechanical Shimano STI hydraulic brake lever provides excellent stopping power with less effort, especially from the hood position. The hydraulic tank provides automatic adjustment of braking performance in case of pad wear. Finely tunable handle adjusters for the levers allow individual adjustment for all hands. Free stroke adjustment for pad to rotor adjustment. Contact levers are supplied without electrical cables as these must be ordered separately to use two connectors for use with E-pipe electrical cables. Weight is 360 grams per pair
