Challenge Tires Criterium Ultra Handmade Tubular

The Criterium is already a super fast-rolling tire with impressive cornering control. This model's silk (seta) casing enhances the tire's suppleness for an even more extraordinary ride. This handmade tubular combines a supple, 1000+ TPI Sealed Silk casing with natural rubber tread with a seamless latex inner tube for improved comfort, 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 low rolling resistance tires.

Sealed Silk
- Silk is a strong, soft, natural fiber casing that unlocks peak casing and tire performance.

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.
