Campagnolo's electronic EPS drivetrains have been highly coveted since their introduction to the market only a few years ago, and thankfully, the trickling down of technology has finally made it more affordable. The Chorus 11 groupset is the latest to be electrified. The Campagnolo Chorus 11 EPS Rear Derailleur you see here is slightly heavier than its Record 11 or Super Record 11 brothers due to the use of alloy structural elements in place of carbon fiber and titanium, but the motors employed are identical, and so thus is shifting performance.
