Shimano Dura-Ace ST-R9270 Di2 STI Hydraulic Disc Lever Left

Shimano Dura-Ace ST-R9270 Di2 STI Hydraulic Disc Lever Left With a raised hood profile and longer hood body; the left Shimano Dura-Ace ST-R9270 Di2 STI Hydraulic Disc Lever offers more comfort and support throughout various hand positions. The hood body houses the wireless hardware that communicates in a lightning-fast manner with the derailleurs just a light touch of the intuitively positioned gear-change buttons on the side of the lever activates the wireless signal; prompting smooth and rapid gear shifts. The unit is powered by a small CR1632 battery that lasts for approximately 1.5-2 years; while ports for additional satellite shifters are integrated to offer even more shifting options. Typically operating the front derailleur; the shifting behaviour of this left-hand lever can be fully customised via the E-TUBE Di2 app. Enhanced braking performance is provided by the carbon lever and its integrated Servo Wave technology that minimises empty lever travel; but increases feel once the pads contact the rotor. In addition; the hydraulic reservoir is self-adjusting to keep the pad spacing consistent as they wear; and a lever reach feature ensures that all hand sizes can comfortably clasp and operate the brakes effectively.
