Dual Control Lever
Like it's DURA-ACE sibling, the Ultegra R8050 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 R8050 shifters feature two e-tube ports and one dedicated sprint shifter port. A pair of them weighs 295g.
