FC-R700 & 105 Front Derailer
Over the off-season I want to upgrade from my 105 triple to a compact double crank. Since my derailers are all based on a triple, I am going to need to replace everything anyways. I am leaning toward a Campy Centaur compact. However, I am intrigued by the Shimano FC-R700 compact crank.
My initial understanding based on some store catalogues was that I would need at a minimum Ultegra 10-Speed derailers in order to use the FC-R700. However, now that 105 is 10-Speed, would I be able to upgrade to 105 and still use the FC-R700?
I tried to find a contact # at the Shimano web-site. Well - they do not provide one, which is irritating, because these questions are typically best answered by the manufacturer. I even examined the technical guide on-line, and it failed to state what derailers it was compatible with.
