I need to convert a Campy record front derailleur from clamp on to braze-on. The picture below shows the parts I need in yellow, but I am ashamed to mention how much the LBS quoted me for just one of the small parts ($65 !!!)
I looked, your shop quoted you a price so high that you wont buy it - probably due to the fact that Quality has none, no ETA and you would never get it. Maybe Gita has it, but I doubt it. That part would have to be imported.
Campy gear is easy to buy and sell on eBay. Why not just buy the one you need used and then sell yours? Also, I am using a 9-speed Campy front derailleur with my 10-speed setup on my rain bike and it works pretty well. You can throw the chain a little easier but if it is adjusted well it works great.
I went through the same drill w/ my older 8-spd stuff when changing frames… just got a whole NOS replacement FD off eBay or about half what a current (then) 9-spd cost, or what your LBS quoted for the small adapter parts.
I believe you can use Record10carbon’s braze-on mounting portion but put your body on it. unscrew part fdre107 and remount the body onto his bracket (i.e.re201).
