The Criterium Tubular is the most versatile and winning tubular in Challenge's line. It's hand made on a 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 in the corners. There's also puncture protection under the tread. Plus, you get a latex tube. Latex tubes are lighter, thinner and more flexible than butyl tubes, increasing your comfort, lowering rolling resistance, and helping to prevent flats, too.
Tubular tires are compatible with tubular rims and are installed with glue or a special adhesive tape. Tubular tires will not work on clincher rims (the standard rim type). If you have any questions about compatibility or mounting, please contact us for details.
