Rim Brake Dual Control Lever (Wired)
The DURA-ACE ST-R9250 Rim Brake levers weigh about 230 g for a pair of levers.
They're essentially the same as the previous generation DURA-ACE levers, except for the fact that they'll work with the 12-speed derailleurs - using the SD300 port type.
Unfortunately, this also means that these 12-speed rim brake Di2 levers are not wireless. You can only connect them to a Di2 system using EW-SD300 wires.
12-speed rim brake shift levers have two SD300 ports and one satellite shifter port.
