Cleaning/oiling ultegra DI2 R8070 rear mech

[E65Ross]

Does this mech require any different ways to clean than a mechanical mech? I last had a 105 mech on my last bike but understand the bearings are a bit different. On my last one the jockey wheels would get quite stiff quite frequently so I had to use a very thin lubricant to get them loose again.

Any special tips, or just a case of wiping the jockey wheels occasionally and then lubing the chain as normal?

What about the front mech?

Cheers

No special treatment to mine - I always wash the bike after a wet ride, particularly a salty winter ride. A few squirts of GT85 (avoiding discs) to displace water and a couple of drops of chain oil on the jockey wheels.

Nice one, thanks for that! What about the front mech? My old one got jammed once due to a load of crud so I used to periodically clean it with a toothbrush and some degreaser, before rinsing it away and then using some lubricant. Would that be safe to do, baring in mind it's electrical? I am assuming all the electrics etc are all fully sealed though, anyway.

I don’t think I’ve touched the front mech apart from a few squirts of GT85. I should note that I have full mudguards which helps to keep the bike clean, but do still thoroughly wash after wed/dirty rides.
