I have 4 brand new, never glued Continental GP4000 tubular tires.

I'd like to swap them for a basic set of tubular wheels for 'cross racing. Wheels need to be Shimano compatible, and silver would be nice.

If your wheels are worth substantially more than the tires, PM me and we can work something out. LBSs sell the tires for $100-$110 apiece, and PBK (who rarely has them in stock) wants about $70.

Also, if you want to purchase the tires outright, please PM me with an offer.
