di2 ultegra rear mech not going on the two smallest cog any tips would be helpful
On the big ring? My guess would be limit screws.
My LBS told me the new firmware won’t let you cross chain small/small.
are you using synchro shift? in which case the clever groupset is stopping user error
on R8000 this does this by design, it doesn't let you cross chain when in the small ring.
