Shimano Ultegra Disc Set Di2 HR STR8070+BRR8070

Shimano Disc Set Di2 HR ST-R8070 + BR-R8070

With its flat-mount design and low profile, the SHIMANO ULTEGRA R8000 series hydraulic disc brake offers more controllable braking in all conditions without compromising the race-specific aerodynamic lines.
The SHIMANO ULTEGRA R8050 DI2 dual-control shifter/brake lever combines SHIMANO's leading hydraulic disc brakes with Di2 electronic shifting. They feature shifters with revised looks and operation for fast, precise shifting even with thick gloves. The new levers also feature a wider grip width adjustment range and a programmable ST button on the top of the grip caps.
