Challenge Grifo Pro Tubular

The best all-around cyclocross tire ever created excels in wet or dry, soft packed, rocky and root-infested courses, grass, and more. The Grifo features fast rolling knobs and a center section that offers excellent pedaling and braking traction. This handmade tubular combines a supple, 300TPI SuperPoly casing with natural rubber tread, and a seamless latex inner tube for improved grip at lower pressures, confident cornering, and quick handing. The latex tube is lighter, thinner and more flexible than a butyl tube, increasing your comfort, lowering your rolling resistance, and helping to prevent flats. The tube also includes a removable core Presta valve. This tire includes PPS, a Puncture Protection System placed between the tread and casing to increase resistance to punctures.
