Shimano ST-R9180 Dura-Ace Hydraulic Di2 STI Right Hand TT Lever

Precise electronic gear shifts, powerful hydraulic braking and reliability are all offered by the Shimano Dura-Ace ST-R9180 Hydraulic Di2 STI Right Hand TT Lever, allowing high specification time trial or triathlon bikes to perform faultlessly across all race routes in all conditions.

Shimano’s Di2 technology is seamlessly integrated into this lever via two, easy to operate buttons. Positioned on either side of the lever, these buttons allow the rider to make easy gear changes when riding through corners and up climbs while the hands are positioned on the outer sections of the handlebars. The Synchro Shift system permits the actuation and behaviour of the gears to be finely tuned, meaning the rider can alter the function of the buttons and the speed of derailleur action in line with personal preferences.

Powerful and modulated braking is granted by the hydraulic configuration and the ergonomically shaped carbon brake lever. The lever has a reach adjustment to instil confidence in all riders, regardless of hand size. The inbuilt hydraulic reservoir tank helps the disc brake pads to auto-adjust, keeping the rotor clearance and stopping power consistent at all times.
