With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the 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. Shifting can now happen as quickly and effortlessly as possible thanks to the super light Short-stroke lever, giving you more time to adjust to the trail ahead. Shifter is completely customizable, using E-tube software you can programme the shifting to your preference. For use with E-tube SD300 electric cables.
