Shimano Dura-Ace R9180 Hydraulic Di2 Lever-Caliper L/R Set

Comprising a Shimano Dura-Ace R9180 Hydraulic Di2 Right Front TT Lever and a BR-R9270 disc brake caliper, this set affords fast gear changes and confident braking when racing against the clock on a time trial bike. The Di2 buttons, one positioned on either side of the lever body, can operate in Synchronised Shift mode with an option to fully customise the shifting behaviour via the E-Tube app. They are 12-speed compatible, and they communicate with the derailleurs via a wire (available separately), guaranteeing consistency and reliability.

The carbon brake lever has a reach adjust feature and smoothly controls the rigid and lightweight, one-piece front disc brake caliper. The caliper houses oversized pistons for even power application on the pads, and these operate with 10% more clearance to minimise brake drag. A redesigned bleed port eases serviceability, reducing time in the workshop for professional and amateur mechanics.
