Description
- 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 customizable shift button placement has been designed entirely by human ergonomics, this means the shift buttons now sit exactly where your thumbs naturally sit
