I'm sure this has been asked before but could I use a campag chainset with my shimano 105 STI levers? I know that this would be bad news with the cogs on the back but is it the same story with the front rings?
It should be "okay" ...
Supposedly, Shimano's pins & ramps are slightly superior ... but, everyone seems to have been allowed to COPY them, for the most part.
FWIW. I can tell you that the 9-speed 105 STI levers will even shift between non-ramped (e.g., 8-speed) chainrings ... I just (as in the last few days), put an old set of
9-speed 105 levers on a bike with an
XT (!) front derailleur & a
52/39 double chainset/(crankset) -- this has to be considered a worst-case-scenario when mating components.
A little fiddling (as with any "new" front derailleur to get the stops), and
voila -- the shifting
seems fine with the bike mounted in a stationary trainer ... well, good enough (for me).
Now, I am able to make the chain
baulk when moving onto the larger chainring when I am when making an indecisive shift OR when
not making a complete shifting motion which leaves the chain in limbo ... and, I can see where having pins & ramps that lead chain onto profiled teeth could expedite the shifting ... but, if I do MY part, then the shifter & chain seem to do what they are supposed to.
Of course, as they say, your results and/or demands may vary ...
