FS: NIB Continental Grand Prix 3000 20-571 tyres

I accidentally ordered a few Continental Grand Prix 3000 tyres in the
20-571 (650x20) size. I've been using the 23 mm version and have
experienced excellent durability and puncture resistance with that
size. Given the rough roads and high speed descents in my area I don't
have any use for the 20 mm version. The 20 mm version would be good for
someone who is lightweight and/or rides smooth roads exclusively and
also would give maximum aerodynamic benefit with deep section aero rims
or disc wheels.

I am offering these 20-571 tyres for $30 each or all three for $88.
