Description
SHIMANO Dura Ace Di2 Disc Brake Road Hydraulic ST-R9170 / BR-R9170 Flat Mount | individually
For the new DURA-ACE Di2 9170 series, Shimano has redeveloped every single system component to create the most innovative component group of all time, to which a disc brake variant is now added.
The R9170 Series Dual-Control Hydraulic Disc Brake Lever, like its shorter-stroke mechanical counterpart, offers a wider range with more range and simplifies gear shifts for quick and intuitive shifting in all situations. The new disc brakes also allow a higher and better metered braking force in all weather conditions.
The Dura Ace Di2 components can be controlled with the Di2 brake and shift levers. A push of a button and the gears are loaded quickly and reliably. The precise pressure point of the circuit ensures that shifts are really only triggered when the driver switches consciously. Accidental switching is not to be feared. The now more defined click gives you the feeling of more control with each shift.
Synchronized Shift allows more efficient gear changes while driving. The function offers numerous advantages such as faster, more precise gearshifts under all driving conditions and minimizes the load on the drive.
