Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

8bits: Clean it with a hose and put it away...

It's the zero maintenance thing that appeals to me.

Go for a proper ride in the country side in inclement weather and you have to run your chain through a chainbath, then re-lube it, or you increase the wear rate by about a bazillion percent.

WIth a belt drive you just lean it against the wall and you're done.

Plus most mud from the trail is piss easy to remove, when it hasnt been mixed with chain oil and sprayed all over the rear end. If things are preety shitty. Just soap it down. If the hubs and BB are well sealed. Theres no need to relube anything.
