Review of Shimano ST-R785 Di2 Hydraulic STI Lever & Disc Brake Caliper Set


The ultimate experience in braking performance is here. The Shimano Di2 R785 Dual Control Lever Set with Hydraulic Disc Brake Caliper is designed for on-road and cyclocross use for more power, more stability and better control. Shimano has successfully paired the 11-speed electronic shifting of their Di2 road line with the mountain bike technology of their hydraulic disc brakes.

Fits a wide variety of hand sizes from the hood position

With unmatched braking shifting options, customization and personalization to meet the various needs of road and cyclocross riders, the Shimano Di2 ST-R785 Dual Control Lever Set for Hydraulic Disc Brakes provides Ultegra-level performance and is compatible with electronic Di2 systems. Ergonomic, svelte design accommodates a variety of hand sizes and provides a comfortable feel that's identical to other Shimano Di2 road shift/brake levers. It delivers fast and smooth shifts with less effort, especially from the hood position, even on the ascents and in the sprints. When joined with hydraulic disc brakes, stopping becomes even more efficient and requires less energy. There's reach and free stroke adjustments, in addition to a pad clearance auto-adjustment at the caliper. Pair these levers with the new E-Tube enabled Ultegra 6870 Di2 or Dura-Ace 9070 Di2 drivetrains, and a growing array of Shimano remote and accessory shifters and electronic components, for access to a fully customizable and programmable shifting system, including multi-shift speed and shift count -- all with the added bonus of future firmware upgrades and improvements.

Fully sealed hydraulic system

Designed to be used with electronic Di2 shifting, the Shimano Di2 BR-R785 Hydraulic Disc Brake Caliper offers Ultegra-level braking in all weather conditions and on long descents. Thanks to the innovative heat management of Ice Technology finned brake pads, stopping power can be tuned to riding conditions, terrain, riders' size and abilities. 2-piston design gives amazingly smooth and well-modulated, mountain bike braking power that is adapted for road use.
