With Di 2 technology shifting is easy & 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 & stretching, & also provides effortless gear shifts.
