The electronic Di2 gear shifting is operated by two buttons on the lever body and can be customised via the E-TUBE app. The gear shift signal is sent via a wire (available separately); guaranteeing excellent reliability in racing situations. The carbon brake lever has a reach adjust feature and smoothly operates the rigid; lightweight; one-piece rear disc caliper. The caliper accommodates two oversize pistons to provide more even pressure on the rotor; and these are designed to offer 10% more rotor clearance to prevent brake drag. The hydraulic configuration has an auto-adjust feature to keep the pad spacing consistent as they wear down; while a redesigned bleed port eases installation and servicing.
