Leve del cambio Shimano Dura-Ace Di2 R9170

These Shimano Dura-Ace Di2 R9170 Shifters are high-quality ergonomically designed hydraulic shifters with electronic shifting. The weight is very low thanks to the use of carbon and composite and the shifters fit comfortably in your hand.
These shifters are assembled and delivered with the caliper already bled. This Dura-Ace combination is known for its high braking power and high modulation, so that you come to a stop quickly and in a controlled manner.
The shifting of these shifters is electronic. They fit perfectly in a Di2 set-up and can be used with all 11-speed Di2 Shimano rear derailleurs.
