Whether the surface is wood or concrete, this unmatched tyre holds the sprinter's line like nothing else. The Pista's silk (seta) casing with more than 1,000 threads-per-inch, a tread that is fast-rolling and grippy in the corners, and our seamless latex inner tube makes for a stellar track tyre 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.
