My FD would work with a Centaur or Veloce, but can the same be said for the IRD Defiant (which I'd actually already started looking at)?
Your front derailleur will shift most anything within reason. Historically the same FDs have been used for 55t timetrial setups to 44t cyclocross setups with reasonable success. Yours has a cage that will probably shift the original 53t best, but shifting a 48 or a 46t big ring will be fine. IRD defiant is really nice and a reasonable option.
