Sorry for the road bike related spam, but all this new fangled kit is a strange new world for me.
Do you use the trim feature of your front shifter, on 11sp road? I'm sure my old Ultegra 10sp had it, but I never needed it. But it seems like on 11sp I find myself using it - when I shift to the big ring I then drop to the trim position for all sprockets except the top three or so. Then onto the little ring it's mostly ok but I use the inner trim position if I am on the bottom 4 or 5 sprockets.
Is this typical? I followed the Shimano instructions for setup, or at least I think I did. It's not exactly clear which position you're meant to be in when adjusting the little ring position.
yes, use all the time on 11 speed Ultegra and 105
Yep, use it all the time too, it becomes second nature (maybe because I so rarely use the top 3 sprockets when in the big ring, in fact it's a noteworthy moment if I have to use the outermost trim position!)
Edit:
It’s not exactly clear which position you’re meant to be in when adjusting the little ring position.
The Shimano instructions I read were quite explicit, I think you shift into the biggest ring then trim 'down' one click, e.g. not far enough to shift back into little ring. That's where all adjustments should be carried out (and where you aim to have the little white lines on the derailleur body lining up).
I think I did trim the front mech sometimes when I was on 105 11 speed mechanical gears yes.
On my previous bike with rival 10 speed I don’t think it was really an issue. I also don’t remember it being something I did on my Caad 9 which had 105 gears (not sure if 9 or 10 speed).
Now on Ultegra di2 and it automatically trims for you - mega!

No, SRAM mechs don't have trim, I think that's what the YAW feature is, the mech moves in a very slight arc perhaps?

Yes, but then the next step - when doing the little ring - it's not clear wether or not they mean the inner or outer little ring position. Or at least from memory it wasn't, I coudl be wrong.
My thought was that it seems more necessary on 11sp than in the past, because of the wider spread and presumably the narrower cage.
Is the trim not just there to stop the chain rubbing on the cage when you’re in gears that cross over a bit? You might be overthinking when you should do it - just do it when needed - I.e you have slight clicking or rubbing.

Well of course, I'm not into doing things I don't need to. What I am saying is that it DOES rub when using those gears I mentioned, whereas 10sp never did. So my question is, is it normal or do I need to take another look at the adjustment?
If properly set up, the trim should let you use all gear combinations without rubbing on the cage.
I use it in the big ring but to be fair, only just discovered it did it after 10 years.

Only works in the big ring doesn't it?
I use my all the time (in the big ring) as I spend most of my time in it, I only use the small ring for climbing anyway so am usually on the top half of the cassette when in that ring (not a humble brag, Iive in SE London, not the Alps).

New 105 has it on both.
Use it all the time on 9/10/11 speed
Yes, definitely have to use it with 11speed. Just got a Campagnolo 12 speed & my impression is that I now need to trim even more.
I use it all the time when gears crossover, down from the top ring and a nudge up when on the inner ring. It’s a feature many people don’t realise is there.
