Hydraulic Disc Brake Dual Control Lever
Like it's DURA-ACE sibling, the Ultegra R8070 Dual Control levers feature hidden buttons on top of the hoods. These buttons can be programmed to do anything. Most riders seem to set them up to change pages on their head unit, or to change synchronized shifting mode.
The R8070 shifters support hydraulic disc brakes and feature two e-tube ports, but no sprint shifter port. They weigh 180g each.
