Italian threaded BB(7 posts)

Italian threaded BBLC
Jul 20, 2003 9:01 AM
I am trying to figure out if an old frame that I got is worth building up. Really nice chromed lugs and stays and apparently from looking at the BB is is Italian, which sounded great till I found out the problems of Italian BB's. Are they really as much of a problem as Sheldon Brown makes them sound, as in will they continually become loose with the right handed threads?

I figured a frame from the bike Mecca land would be perfect. How could Italians screw up like that? I can understand the French doing something like that, but not the Italians! Are most Italian bikes still like that?
What are you trying to accomplish?Spoke Wrench

If you're talking about using all or mostly all new parts, you aren't going to save very much money over just buying a whole new bike. The Italian bottom bracket wouldn't be a deal breaker for me, but a 120 mm or 126mm rear triangle might.

I think Sheldon makes too much of it. I had one loosen. Never happenend again after I started tightening them extra tight. Campy insructions say 51.66 ft pounds.I got 7 frames that use Italian,threading,so there is really no good reason no to do it because of that issue.

I have two bikes with Italian BBs. The only one that ever came loose was the one I installed without using a torque wrench. Since torqueing it to the correct spec it has not moved. Some folks (myself included) use teflon tape on the fixed cup as extra insurance. Can't hurt. No need to be paranoid about Italian BBs.
Good to hearLC

I have a deep enough parts bin to build it up at nearly no cost, but I would have to get a new Italian BB, as the one in the frame is pretty beat and seems to continually loosen even on short test rides. She only groaned a little as I spead her from 126 to 130 spacing ;)

Just torque it to proper spec and use a bit of blue locktight on the cups and it won't loosen until you want it to.

yup...but don't let it stop you from getting an Italian bikeColnagoFE

It's not that big of a deal. Just check torque every so often. A bit of teflon tape on the threads can help as well.
