Orbea Bottom Bracket shell woes
Hey y'all.
Here's the short version. -Get hit by a bar, wreck the frame. -Find seemingly awesome deal on an old Orbea with an "English BB shell" -Order a BB at the LBS, it arrives... -LBS: "Whoops, frame's Italian threaded," so I get an Italian BB -LBS: "That didn't work either b/c the shell's threads are toast" -At home, the old fixed/LH side cup threads in well (right/tight) -Also, the same fixed cup also threads in well on the RH/drive side -New Shimano 105 English BB threads in well on RH/drive side ok. So both sides are RH threaded, 1.37" x 24 tpi? I don't see that he http://sheldonbrown.com/bbsize.html#threading Is it possible that it's French threaded and the Shimano went in there b/c the threads are indeed toast? I'm at a loss here. Thanks in advance, -- \\paul (replace all caps with numerals) |

Orbea Bottom Bracket shell woes
I have built up two new Orbea frames and both were English thread, and I believe they have been using English thread for some years now. Depending on how old your Orbea is it may well be a French thread. France is just up the road from the Orbea factory (relatively speaking), and is one of their biggest markets, so they may have used French thread to make the frogs happy. This is just a theory though, I may be completely wrong. "Paul Hobson" wrote in message ... Hey y'all.

Thanks in advance, -- \\paul (replace all caps with numerals) Sounds like it was English, and somebody chased the drive side with the wrong (left side, rh thread) cutter. I'd try cutting it with the correct cutter and using a bb/crank like Shimano Ultegra external bearing type so the crank helps hold it together. If the threads are really hosed, maybe try converting them to ITA. Good luck! Joseph |

I'm guessing, in this soft, aluminum frame, somebody rammed a right threaded but wrong side BB tap into the shell and then finished the 'mistake' making them clean. It isn't Italian, a english cup would just slide in as the ID s bigger with Italian. |

Thanks in advance, -- \\paul (replace all caps with numerals) Common suggestion round these parts is to resize/rethread the bb shell to Italian threading. Other suggestions have been to fill the threads with brass and re-tap. I like the first suggestion, although then you are dealing with the inferior Italian threading and it's greater tendency to loosen. D'ohBoy |

I don't know if this changes anything in your assessment, but the frame is certainly steel. Maybe I'll call around to see if any one can ream it out to an actual Italian threading (since I happen to have this DA bb just sittin' around). somebody rammed a right threaded but wrong side BB tap into the shell and then finished the 'mistake' making them clean. It isn't Italian, a english cup would just slide in as the ID s bigger with Italian. Thanks for the knowledge. \\paul |

Would you recommend boring the BB shell out to Italian thread (hard to get a bike shop to do that locally)? Or would it be better to just fill the non-drive side with brass and face/tap that side, leaving the other side to be faced/chased? |
