Italian bottom brackets coming undone

[biggs682]

Had the great experience for the 3 rd time in about 5 years of a drive side bottom bracket cup loosening on a ride , when it happened the first time my lbs told me it's quite common and the easiest repair was to fit a threadless unit in its place and that is what i have done the 2 previous times ?

Any other ideas or suggestions ?

Threadlock ?

Locktite and do it up bloody tight?

The only time that happened to me (On a bike I'd newly built) I just tightened it a bit more. You could also try a semi-permanent grade of Locktite.

Is it the same direction as normal ?

Italian bottom brackets have a right hand thread for both cups so the drive side has a tendency to come loose. Bitd this was solved by brute force tightening

I'd use Loctite 262, it will release after heating to 250 Centigrade.

Going to try the bit more brute force over threadlike or supeglue so will see

I have seen this referred to as RFT..Really Flipping Tight.

When I was a technician we called it 12 ducks is the number of times the wheel nut gun made a noise when tightening them up

I have the same problem with the cup on one of my Pugs which has a french threaded BB. I added a bit of threadlock and then did it up real bastard tight, has held tight since then and I've done about 2k miles on it. You don't really have much other option unfortunately as has already been said above!!
