BB Cup Removal??
I am in the process of overhauling a old Colnago. I have reached a road block in removing the drive side cup from the bottom bracket. It is a campy bb that is an oem part on the bike. I think it is a reverse thread(english) but from doing a search on the board I maybe wrong in my assumption(italian). Can someone please help?
Another questions, can anybody recommend a cartridge type bb for this?

Are there any numbers or letters on the drive side cup?

This is what the cup reads. 36 X 24 F Brev Inter Campagnolo. I hope this helps?

BB axles come in different widths, so don't do what I've done, and buy one that's too narrow for the cranks (I barely had the crank on the axle, and the chain ring was rubbing on the chain stay), or too wide for your gears.
D'OH!

If you are keeping the Campy crankset, go with a new Campy ACH botttom bracket. The tapers on Campy and Shimano are different. I got an English threaded ACH from Branford Bike for $30 this past winter., but Italian thread is available as well.

How old is the Colnago?

If you have a good shop respace the rear end for a modern drivetrain, you could build it up with all new stuff. You might be better off keeping it vintage, and getting a new bike.

If I keep the bike vintage it will have to keep it fixed gear. Most of the old campy parts have been lost. I was thinking of picking some parts off of ebay to fix the bike up
