Dual Control Lever
These ST-R9150 Dual Control Levers are the DURA-ACE R9150 rim-brake levers.
They weigh about 115g each and both levers have two E-tube ports and one remote sprint shifter port. If you're looking for the Hydraulic Disc levers, visit the ST-R9170 hydraulic disc lever page.
Just like the ST-9070, ST-R8050, ST-R8070, ST-R9170 and GRX levers, these ST-R9150s have a hidden button on top of the hoods.
I wrote an article on setting up the Di2 shifter hood buttons, so have a look if you haven't set yours up yet.
