I have another old Bianchi road frame coming my way and I'm looking trying to have an idea as to what specs I need in a bb to accommodate it.

I'm already assuming that I'm going to need italian threading, I'd like sealed cartridge bearings, however my uncertainty lies in the axle/spindle dimensions. I'm planning on putting on an old TA double crankset on there. Right now I'm thinking of something along the lines of a recent campy that would accomodate a double so 105mm?

Any input would be much appreciated as my experience is limited when it comes to not only bottom brackets, but vintage frames as well.

Thanks much! :D

I'd be guessing it would take around 115 to 120mm. Maybe JohnE has the scoop on this one :)

Spindle length needs to be matched to crank.Don't know the specs on the old TA stuff, but alot of the older stuff used the longer spindles.An e-mail to Sheldon Brown at www.harriscyclery.com may get you the answer.He knows the older stuff and does reply .
