Disc Brake Dual Control Lever (Wireless)

Disc Brake Dual Control Lever (Wireless)


Twelve-speed GRX Shift levers feature one SD300 port, one satellite shifter port, and three shift buttons.

The third button isn't on top of the shifter but on the inside, where you would rest your thumbs.

Like the 105 Di2 shifters, these GRX units take two CR1632 batteries. They should last for about 3.5 - 4 years.
