Heavily used and scratched CX frame?
I have built up an old Peugeot as a "cross" bike that I use for both commuting and racing (this cross stuff is addictive). The frame was originally made for 27" tires so with long reach brake calipers it was able to take 30mm tires. After a couple of muddy races and riding it in the snow I found myself wishing for more mud/snow clearance, it actually get's stuck in the break calipers.
Trick is that's my commuting bike too and if I go out and buy a new frame I am definitely increasing chances of it being stolen. Right now, it's a pure "stealth" bicycle - the dinged-up frame, combined with the dirt masks the fact that it has part-ultergra, part DA 9-speed group and a pretty good (though not too blingy) wheelset. I am forced to lock the bike up at the train station without a guard, so I have to maintain the "stealth" quality as much as possible.
This said - is it possible to find someplace a well-used but quality cross frame, something that has been raced for some 5 seasons, has scratches, bumps and peeling paint? I looked on Ebay and CL, but no luck so far. Are there team liquidations or something of that sort that I could latch onto?
