Left main lever assembly Shimano ST-R9150

Product Description

Essential component of the electronic transmission system of the Japanese manufacturer, the left lever SHIMANO Dura-Ace Di2 9150 offers an even better control on the gear change and on the braking! Even lighter and more ergonomic than the previous generation model (9070), this lever offers a very comfortable grip!

On the technical side, the Dura leverAce Di2 evolves in its 9150 version: the action on the control is sharper and more precise, for quicker shifts ultra and an improved feeling during the race. The other innovation is the possible synchronization of the gears (Semi Synchro Shift technology), inspired by the XTR Di2 off-road model: the action on the left-hand control alone automatically adjusts the selection of the sprocket on the cassette, so as to maintain its cadence and an optimal chain line!
