Which Groupset?

Yes because they are a smaller company, and decided to focus on 11spd instead of EPS.

Are you even listening at the back?

An interesting turn of events happened that changed the order of which company introduced electronic shifting to the market first. Campagnolo’s 10-speed electronic shift components were ready for the market in 2005, and it planned to introduce them. However, after a successful Giro d’Italia campaign with Illes Balears-Caisse d’Epargne, a number of the bikes failed to shift after being driven to Trento in driving rain at 150kph. The system worked after it was dried out again, but this is exactly the kind of thing that keeps electronic-shift engineers awake at night. This snafu stopped the progress dead in its tracks, as the company had other fish to fry and could not afford to devote resources to this project at the expense of its core business.
It continued to work on the system, but slowly. In 2009, Campagnolo introduced 11-speed drivetrains at a number of price levels, so all of that changeover, performed in secret, required the undivided attention of Dal Pra and other engineers.
