It's definitely fixable, but you'd need some expertise to get that insert out without damaging the frame. call calfee, see if they do it.

This should be a warranty item though, might be easier to warranty the frame.

Thanks for the reply. I'm going to try to do warranty, but this is actually the second time there's been a bottom bracket problem with this frame. The last time, it cracked and they sent me a new one through warranty. But even then, going through the shop I bought it from, Guru was reluctant to replace the frame and I had to wait a long, long time. Now, about 1.5 years after I got the replacement it goes again but that shop no longer sells Guru so it's basically gonna be me emailing/calling them about it. I'm not optimistic about the outcome. They don't even make this frame anymore.

curious what Guru model it is? I have a Flite
