Ignore me if it’s Di2, but otherwise I’d check the shifter for any frayed cable, and at the other end I’d detach the cable and check for grot in the cable outer.

Why don’t you detach the cable and see if it springs into the smallest cog no issue - oh should have refreshed

New cable?

I could change the cable and see if it fixes it....
It's a good place to start.

I think it might be the cable
It is. New inner and outer will fix it.

I'm a bit mystified by this.
My rear mech (105, pretty new) was working fine and indexed perfectly until last week.
Now it doesn't want to spring back when I upshift. It will eventually get to about sprocket 9 of 11 but not all the way. If I push it manually it will get into the two smallest sprockets so it's definitely not a limit.
It seems like the spring has either suddenly lost power or is being blocked in some way, maybe by dirt.
It happened after a dirty wet ride 10 days ago. I've just cleaned it properly, which I thought might fix it but it hasn't.
Any ideas?
Edit: so I think it might be the cable as when I feel the bit of cable between the two bits of mech it is tight, until I press it to make it come through.
But maybe the mech spring should be doing that job and overcoming the friction that's bound to be there...?
