Hi,

I cannot seem to find any info on the BB-size of a Colnago CT1 B-stay frame. I'm getting the frame soon and need to know if I need a new BB or can use my old one (Ultegra 109mm). Anyone out there who can help me?

Thanks,

Jowan

Italian and english.What do you have?
109 is the width of axle and should work.
Last time I built a colnago it had itlalian threads.
I am sure they still are but with the way things change
you never know for sure. ask cc 1 800 688 8600.
If you dont have the BB you need you can pick one up from them for around 40 bucks.

You need a 70 mm diameter Italian threaded BB. The 109mm length will work if it is Italian threaded.
