>>1151524The bottom bracket is likely to be Italian threaded (ask). Your frame, unless it's an italian road frame is probably british threaded.
The bottom bracket is likely to be worn and want replacing even if it's compatible with your frame. Campagnolo cranks use a different taper size (ISO) as opposed to the more common square taper that shimano and most others use (JIS). Campagnolo square taper bottom brackets are available, but quite expensive.
That mech on the left is missing the mounting bolt. The jockey wheels for it look shot. I think it's an 8 speed mech. That's probably 8 speed downtube shifters as well. If you want them to index, you will need an 8 speed campagnolo hub and an 8 speed campagnolo cassette. Nothing else is compatible. I believe you can modify the shifters to be friction and then you could use any shimano hub and a reasonably narrow shimano 8spd cassette with it and the derailer on the right even if it's shot.
Retrofitting old single pivot campagnolo brakes seems madness to me, although set up well with new pads & cables they will be alright. If your frame is newer, there may be an issue mounting them.
You will need campagnolo cables. They have smaller heads. Shimano definately will not fit in the shifters, and probably will not fit in the brake levers. Or you could ghetto some shimano cables with an angle grinder or a file but it would be a bitch.
An FD clamp will probably be allg
Do you have a / is the headset ok?
You can polish and sell that post for $$ if it's too short
Post a pic of the frame? Do you know it fits you? Will it suit sexy old campy? A new 10spd tiagra groupset including bb, all cables, new brake pads, cassette & chain is $325 on wiggle. That would ride a LOT better and be easier, although still a few compatibility issues.
