Challenge's Forte Tubular has an aggressive tread for an excellent ride in wet weather. It's hand made on their supple 300tpi SuperPoly casing with a durable tread compound and tough polyester in the sidewalls. The center tread rolls quickly while the side tread sticks to the road in the corners. You also get a puncture-resistance layer beneath the tread and 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.
