• di2 is ridiculously simple. Take it out of the box, push buttons and ride away.

    I adjusted the shifting only once in 3 years. And you can do that on the fly, like a mechanical groupset.

    No need to replace inner or outer cables and if you find out half way you forgot to charge it you can always just push your derailleur into a gear and ride home. It's a lot harder when you snap a (mechanical) cable.
