Anyone know about these things? My BB shell is looking badly stripped and the chap at the LBS was not hopeful about re-cutting the threads. The solution - a threadless BB unit (or an expensive re-fit at Argos). How robust are they?
I used one for awhile on my commuter bike (can't remember what make tho', it's the one Beyercyles have on they're website- I can't imagine it's been updated recently). It was OK, but it did tend to work itself loose- they need to be done up really tight. I used threadlock to keep it there after the first couple of times it worked loose.
It was a temporary measure for me, I eventually got another frame off ebay.
It is possible to restore the thread in your BB, what is the frame made of?
One solution could be braze which can then be re-cut, there are other things out there for such purposes, including alloys which use the braze principle.
I'm a member of www.mig-welding.co.uk, the guys on this forum are incredibly helpful and I'm quite shore would offer some very good advice, I'd suggest putting a post with pictures onto the forum and seeing what the responce is.
I don't think that the BB shell needs to be replaced, have you asked a frame builder about thread restoration? Probably a safer bet than the LBS anyway.
Ain't no frame builders near here. Nearest would probably be SJS or Argos. Replacing the BB shell with Argos would be the thick end of £100. I'm going to go with the threadless solution for the moment, the BB is about £13 so if it doesn't work then I won't have lost much. At the moment I don't really have the time or contacts to pursue the other options, although they may prove more effective in the long run. I'll certainly bear them in mind, Cheers for the advice, not a solution I've ever heard of before.
