This answers your question.
No, you don’t want to be **** around with having to charge batteries on your commuter bike, which, if like mine, will get attention if, and only if, it’s falling to bits.
This is rubbish.
A Di2 and hydro disc equipped commuter requires FAR less maintenance than something with cables. I commute around 7000km a year on a Di2 commuter and have done for 8-10 years. Only once have I had a nearly dead battery (totally my fault – kept forgetting to charge it after very long days at work) and I only have to charge it 3 times a year. No cable stretch, no rusting of inners and outers, no freezing of cables inside the outers, no chattering of slightly misaligned gears.
The only fault I’ve had is a worn wire near a frame entry port which eventually caused a battery drain. £15 to fix. I’ve not bought any cables, ferrules, outers, nothing for almost 100k km!
