Can you really cross the chain completely without any chain rub ? (Big ring, small cog and vice versa ?)
I really enjoy my da 77000 triple on my commuter bike but i think it's impossible for me to set up without chain rub in the extreme positions. And after every 6 month on commuting i need to play a little bit with the derrailleurs settings.
It's a second hand groupset and i use it every day since almost three years. I think the groupset start to be a little bit tired and i am thinking about getting a new transmission. I like my 1x11 on my mtb but for a "road" bike i was more tempted by a 2x with a compact crankset. Have you any recommandation ? I live in the alps so some climbs are quite steeps.

Yes. I have Sora R3030 setup on tourer and get no chainrub using full extend of the cassette / chainring .
BUT that is with trimming.

As @King_Saxlingham said, you can, I believe this is why people generally don’t like triple; you can’t always get it to not rub until the late ‘10 where Shimano finally got it to work well with their mid to high end road groupset.
(Ignoring the fact friction shift is another way to get zero runs).

What your smallest ring? If it’s 30, then a 46/30 would suffice unless you like to grind heavily.

That’s the thing, only recently I was able to get a triple to work with the trims and zero chain rub (Sora triple for example), I always expected a little chain rub or two but zero on the modern triple.
Plus, with 11+ speed, there’s very little need for it nowadays when it offer a big range without a massive gap between each sprocket, having said that, would be great to have an almost straight block with a triple 11 speed drivetrain.
