SYSTEM OVERVIEW
SHIMANO ULTEGRA Di2 R8170, specified for the build.
R8170 is the hydraulic-disc control family within the current 12-speed ULTEGRA Di2 system. A trade package can be assembled in several valid combinations, so we confirm the crank, cassette, rotors, wiring, battery, and small parts before pricing the order.
Performance 12-speed system
The 2 × 12-speed architecture is built for fast road shifting, with gearing selected around terrain, rider needs, and the target bicycle.
SERVO WAVE brake control
The R8170 hydraulic control platform is designed around Shimano's SERVO WAVE brake-lever technology for modulation and control.
