Shimano Di2 Disc Brake Set 1000/1700mm ST-R785PA1 Pair With BR-RS805 – Post Mount

Shimano ST-R785 + BR-RS805 Hydraulic Disc Brake – Post Mount

SHIMANO is well known for their high quality hydraulic disc brakes in mountain biking. After intensive testing SHIMANO launched today a future direction in road braking: hydraulic disc brakes for on road usage with electronic Di2 shifting. The BR-R785 hydraulic disc brakes maintain high consistent braking performance regardless the weather conditions through innovative heat management and brake power that can be tuned to riding conditions, terrain, riders’ size and abilities.

The advantages of Di2 (Digital Integrated Intelligence) are clear for everybody who has tested it: changing gears becomes easier, effortless and faster by simply touching the shift buttons. Control at the top of your fingers. Additional benefits include an automatic trimming front derailleur, unmatched precision plus super easy installation and adjustment. This allows automatic chain guide movement in response to the gear position of the rear derailleur. There is no more need for concentration on trimming when riding.

Dual control lever ST-R785

Despite the integration of a mineral oil reservoir in the lever SHIMANO’s engineers were able to develop a compact Di2 dual control lever (ST-R785) to create a comfortable and natural hand position for all day riding comfort. When descending with rim brakes riders use much power and energy to stop for a turn or even a hairpin. Hydraulic disc brakes have more stopping power and allow riders to brake more efficiently with less energy.
