This auction is for two rare handmade tubular cyclocross tires. The wheels are not included in this auction. These 700c tires incorporate the tread of the fast Continental Speed which is mated to the famous Challenge 260tpi casing (Italy). You have to be on a pro team or know someone to get these usually. Very trick indeed.
Tire specs:
Width: 35mm on label, 33mm actual
Tread: file center section, small lug edge
Casing: cotton 260 TPI 30-90psi with sidewall sealant applied when tires were made. Please read about challenge here: http://www.challengetech.it/info/technology/en
These tires were on a demo bike mounted to the new WH-7900 DuraAce wheels (not included) in the pictures. They may have a few hundred meters of riding on them and thus the new(other). These are presta valve. Glued once for demo purposes. The feel of the casing reminds me of the old vittoria tubulars, my favorites. Ask any questions. PayPal only please. Shipping within the 50 United States is free and I will not ship anywhere else. Local pickup in the San Francisco area is allowed.
