    You need to seek out a Trek dealer. Your frame will likely need to be replaced or sent back to the factory to have repairs made.

    You mean the threads in the BB is buggered? The shell itself hasn't come loose from the carbon-fibre right?

    What I would do is bore out the BB about 1/2-way through the thickness of the shell. Then get a replacement BB shell and spin that down in diameter to press-fit into original bored-out shell with 0.001-0.002" interference fit. Use some 2-part epoxy as lube and once it's in there, it'll be as good as new.

    Basically same procedure as sleeving a worn-out cylinder-block on auto engines.

    I doubt that Trek will sell you the part you want, but here's the information you wanted:

    Trek Bicycle Corp
    801 West Madison
    Waterloo, WI 53594
    920-478-2191

    If you are the original owner, I suggest you take the bike to your dealer and pursue a warranty claim. Your problem certainly sounds like a warranty issue.

    How old is the frame. OCLV has a finite useable life.

    As I recall, this was a common problem with early Trek OCLV frames and is indeed a warranty issue.

    In late 1997/early 1998 they phased in a new, much improved bottom bracket shell. The original shell wasn't bad, but because the internal aluminum sleeve ended flush with the carbon fiber surrounding it, it was possible to put a compressive load on the carbon when installing a bottom bracket, which, in some cases, caused a disbond between the aluminum shell and the surrounding carbon. This didn't happen often, but we did see some frames that had to go back for replacement (under warranty) of the bottom bracket shell.

    The new bottom bracket shell (still in use today) has the aluminum internal sleeve going all the way out past the end of the carbon part of the frame and over the edge, so that there's no possible way to make contact or compressively load the frame when installing a bottom bracket. It's also a bit beefier overall in the carbon part of the fitting, which has virtually eliminated the issue of an under-shifted chain chewing a hole through the chainstay (although that wasn't an issue anyway as long as the adhesive stainless steel chainstay plate was in place). The beefier design is something some people find a noticeable improvement in climbing & sprinting.

    I would contact Trek directly and try to get it resolved as a warranty issue. You can try using their online contact form.

    For whatever reason, the OP must not have a warranty or he would have taken the bike down to the nearst Trek dealer and demanded a new frame.

    Most likely he bought the bike used. I believe the warranty applies to the original purchaser only.

    I suspect he is screwed. I doubt that Trek sells the part he needs. That's up to Trek, of course, so he really needs to call them up. But I suspect he's going to have to ither pay a machinist to construct the part or buy a new frame.

    I am interested in how it turns out though. I have a couple Trek bikes (with warranties) and it would be good to know their policy on selling subassemblies.

    Trek may still be able to do something for the OP although it might result in a repair bill. I would still attempt to contact Trek first.

    if trek will warranty it, the frame should be free, but if you don't have a good relationship with the shop you take it to, or you didn't buy it from that shop, be prepared to pay up to $200 in labor for a tear-down/rebuild of the bike.

    contact a trek dealer and get the skinny on warranty. they're still doing warranty replacements for the lipped icon quill stems, so i'm sure your frame would be covered...
