Hi i just spent the best part of £350 on my bike and today was the first ride with all my new parts and i noticed that the bb was unskrewing its self so i went home to tighten it back up and the thread is stripped. Just wounderd if you can go places that re cut the thread as it would be a cheaper option thean buying a new frame.

Thanks .James

Frame is about 12months old and it came with bb and when i took to the local bike shop they said it was most prob a naff fitting and when i changed the bb it took the thread with it.

you may have to prepare for your frame to be f@$ked . sometimes it can be re-cut if you have only striped like 10-20% of the Fred .

id say take it to a good bike mechanic they might be able to bodge it back in for you if they cant fix it

It is possible to have a sleeve fitted if it's beyond retapping, with the threads made from the new insert. Somewhere in the region of £50 from Argos if I remember correctly

Alternatively, you can buy bottom brackets which thread into themselves, so don't need frame threads. Could be an option :)
