Shimano Dura-Ace ST-9250 Di2 STI Mechanical Lever Left

The Shimano Dura-Ace ST-9250 Di2 STI Mechanical Lever Left is designed for use with traditional rim brake calipers and possesses an ergonomic hood shape to ensure comfort and control. The hood body hosts SD300 wire ports, that when used in conjunction with an SD300 wire, communicates with the derailleurs; pressing one of the ergonomically shaped shift buttons on the side of the lever rapidly sends a signal to the derailleurs, activating a smooth and crisp gear change.

This left lever is usually set up to work the front derailleur, but using the E-TUBE app, its behaviour can be entirely customised, while an extra SD300 wire port is included within the design so that an optional satellite shifter can be installed. The carbon brake lever guarantees accurate and powerful braking when used in conjunction with a Shimano SLR rim brake caliper and its reach can be adjusted to make sure even small hands are catered for.

Please note, an SD300 wire will be required to connect this lever into the 12-speed Di2 system. This is available separately.
