Whether the surface is wood or concrete, this unmatched tire holds the sprinter's line like nothing else. The Pista's silk (seta) casing sports over 1,000 threads-per-inch, a tread that is fast-rolling and grippy in the corners, and our seamless latex inner tube for a stellar track tire that's race-day light, super-supple for a sweet ride, and ready to carry you to victory after victory. 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 tires combine many attributes to create the most comfortable and lowest rolling resistance tires.

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

- The S stands for Softer and more Supple. This tire utilizes a softer durometer tread rubber especially valuable on track and cyclocross tires.

- Latex tubes are stronger, lighter, super supple, absorb shock, and conform precisely to terrain, reducing rolling resistance.
