With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.
Shimano's FIREBOLT customisable shift button placement has been designed entirely by human ergonomics, this means the shift buttons now sit exactly where your thumbs naturally sit. Shifter is completely customisable, using E-tube software you can programme the shifting to your preference.
Right hand band clamp mount type. For use with E-tube electric cables. 11-Speed.
