Which derailleur?

Hi, Can someone explain to me the difference betwen band-on and braze-on Campagnolo front derailleurs? How do I know which one I can use - or have to use - for a Colnago C50? Thanx.

Some frames have a small bracket brazed to the seat tube. This is used to attach a "braze-on" front derailleur. Without this bracket you must use a derailleur with a clamp. The C50 is carbon fiber, I think, so it would not have a braze-on bracket. Be sure you get the right size clamp for your seat tube.

Duo about the c-50 but there are CF bkkes that take a braze on FD.

Yes there are. I have a full carbon frame with a braze on mount, but it isn't actually brazed on as that would be very bad for the carbon .

My C50 has a braze-on front derailleur.
The braze-on types are normal for CF frames. The bracket is fastened to the tube with rivets or screws, not actually "brazed on" as they may be on steel frames.
