Really like these hub and derailleur setups and see they are making a comeback on 1x road and gravel bikes. Didn't realise that Sachs did a two speed hub, looks good

This kind of thing must be the future.
It's getting daft this constant adding sprockets, messing around with wheel dishing, poor chain lines, then changing the rear OLN another 3 or 5mm, and all the time trying to keep Q-factor in check so your heal doesn't hit the chain stays.
