Shimano R785 hydraulic disc brake calipers features a two-piston design with mountain bike stopping power that is tuned for road use. Heat reduction in the caliper is further enhanced with ICE Technologies finned disc brake pads that reduce heat by 50 degrees. Shimano's proven Di2 electronic shifting and ICE Technologies hydraulic disc brake heat management systems enable the new Ultegra grade R785 series Di2/hydraulic disc brake system to provide powerful, dependable disc braking performance that is functional for a variety of cycling uses and conditions. Di2 Levers and Rotors sold separately.
Hint for breaking-in: New disc brake pads require a certain break-in period in order to provide the full brake power. The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stops braking from a medium speed. Attention: the rotors get very hot, do not touch them!
