Challenge's Criterium 320 clincher is hand made on their light and supple 320tpi CoreSpun woven-cotton casing with a long-wearing tread compound. The center tread rolls quickly while the side tread sticks to the road for awesome handling. There's also puncture protection under the tread.
This is a folding clincher tire.
