Help please - What BB type for chorus graphite?

[theup_cyclist]

Hi peeps,
I've just bought a chorus graphite chainset from a forum member.
Need some guidance on which bottom bracket to source to go with it.
It's for a colnago super late 80s.
Thanks in advance.

Hi, Chorus of that generation uses 111mm spindle if your frame has a 68mm bottom bracket shell , you obviously need to find out if your frame is English or Italian thread etc .

Re:

would it not definitely be italian threading if it's a colnago?

Yes, it will be Italian. The Centaur 111mm BB is rather good, you can dismantle it and fit new bearing cartridges.

Re:

Does it matter if it looks like a cartridge type BB or one with individual pieces?

Re:

A cartridge would be cheaper and easier to fit if you`re not that experienced , I have used these in the past with campagnolo Chorus and they are a lot smoother than the original chorus BB

I make no recommendation about the retailer , its just for example of a suitable BB ( be careful to order correct size as per earlier post.
