    My bike needed an new bottom bracket so I splurged on a campagnolo crankset/bb. I took it to my local high end shop (http://www.glorycycles.com/) to get the repair done. It turns out my bottom bracket shell/threads are completely thrashed, which is not my doing (40 year old frame). I know Bilenky could do this, but $200 is kind of steep. Then again, i want the repair to be done properly. Anyway, has anyone had experience with something like this, and if so, who could do it the best? Thanks

    I forgot where ive read this but i heard something abut threadless bottom brackets for stripped threads
  3.  
    isnt the bb30 bb threadless?
  4.  
    I read about velo Orange making a bb for stripped threads, but my bb shel is ovular, so that wouldn't work.

    Posted By: idrinkwatermy bb shel is ovular


    explain? i dont understand how this could work on a threaded object. and if you are taking about the shell itself being ovular the actual threading should still be cylindrical...

    or am i un-educated, i've never heard of such a thing.

    edit: i assume this is going on your atala, that means "ovular" doesn't equal "eccentric," which was my only guess.. i'm def overthinking this. i don't see why the VO bb wouldn't work.

    The actual bb shell is bent out of shape, and so is the bottom bracket i have, so a new circular bb won't fit. This is why i need the whole thing replaced.

    i see... and understand. i guess i just thought that the threads were just messed, not the entire bb shell. sorry bro, my bad.

    i wish i had better advice but unless you are chummy with a builder $200 sounds pretty appropriate with all the work that goes into rebrazing a bb shell. i think the frame is worth it though..

    Has anyone had experience with wildframe in atlanta?

    I had looked into getting my frame professionally painted by an outfit in Georgia near Atlanta called AirGlow. I like the way they work.. Anyway this is their URL and what they have to say as professionals about WildFrame:

    I guess whoever you went to see was too lazy to get their BB tap set out and chase the threads for you. Even if it is slightly ovalized, the tap will still line up and just cut the threads deeper. It's a big enough diameter that there will still be enough thread contact.

    This is the reason I just go to bike shops for parts, and I've learned how to do everything else, half the people who work in shops either don't want to go out of their way to work on shit or don't know their asses from their elbows.

    From what I understand, a previous owner killed the bb shell, jammed a bb in and welded it closed. I don't think the threads really exist anymore.

    Well without pictures it's impossible to say whether it can be repaired or even how. I have seen some fucked up bodges restoring old motorcycles and motorscooters where you don't have spares available so you fix what you have, and you make it look like it's supposed to.

    A common way to fix internal threads is to weld them up, then mill it to the threads inside diameter and then re-tap it. I think that is way less invasive than heating up 4 tubes and yankng the BB, and then get that pinned back together and everything aligned and then brazed back up.

    Like I always say:

    If they say it can't be done, it just means they can't do it.
