That really sucks. If you have links to photos of said bikes that might be helpful, just in case someone spots something. I assume you're going to keep an eye on the usual suspects/craigslist postings. If you normally ride a 52, I'll see if we have anything used kicking around at the shop that would fit you. For new stuff we have some Steamrollers in right now and I can certainly give you the "make life a bit better" discount.
