Description
The carbon bladed Shimano Dura-Ace 9180 Di2 TT Shifter/Caliper - Left Rear performs both braking and shifting duties as part of an electronic Di2 system. One of the beauties of electronic shifting on time trial bikes is that it can be controlled from either the bar ends or the brakes to allow the right gear to be selected whatever the hand position, and corners to be exited as rapidly as possible.
The shifting functions can be programmed to personal preference and are Synchro shift compatible, allowing a single shifter button on either side to control both front and rear shifting. Both reach and free stroke can be adjusted to suit all hand sizes. The brake caliper uses an oversized 22mm ceramic 2-piston design for heat insulation and optimal pad wear.
