Disc Brake Dual Control Lever (Wireless)

ST-R9270 - Disc Brake Dual Control Lever (Wireless) image

The ST-R9270 Hydraulic Disc Brake levers weigh about 175g per lever.

Just like the previous DURA-ACE dual control levers, these have 'hidden' buttons on top of the shifter hoods. You can set these up any way you like and I wrote an article on just that: setting up the Di2 shifter hood buttons.

Wireless and wired

While these shift levers support the new wireless Di2 shifting, you can also choose to connect it using EW-SD300 wires. Doing so will improve battery life by approximately 50%.

12-speed disc brake shift levers have one SD300 port and one satellite shifter (SW-RS801-T/SW-RS801-S) port.

Updating wireless levers

While you can customise these levers and change button assignments using the mobile app, you cannot easily update them. The levers need to be wired to the rest of the system in order to enable updating via the mobile app.

I have written a guide on updating 12-speed wireless dual control levers. Read that if you're stuck updating your levers, or simply send me a message.
