700c, 27-Inch & 650c

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. Handmade - Handmade tires combine many attributes to create the most comfortable and lowest rolling resistance tires. Latex - Latex tubes are stronger, lighter, super supple, absorb shock, and conform precisely to terrain, reducing rolling resistance. PPS - The Puncture Protection Strip is a special fabric placed between a tire's tread and casing to increase resistance to punctures.
