I seem to have some trouble shifting from the big ring down to the small ring. Sometimes I have to push shifter 20+ times before it finally shifts. I know ..... Just HTFU and keep it in the big ring
. I took to LBS and it shifted perfectly every time while on the stand. I don't know if it's an issue with the brifter (DA) or the FD (ultegra). Was thinking of buying a DA 7800 FD to see if that would fix the problem, plus then I'd have a full DA drive train. Thoughts?
