The Schwalbe Ultremo TT Tubular Tire takes the uncertainty out of which tubular to choose for the most important race days on your season calendar. Its extraordinary grip and supreme comfort has made it a favorite among even the purists in the professional ranks.It?s essentially the Ultremo HT Tubular without the extra weight of the puncture protection belt. That weight savings makes it perfect for your race wheels, especially for those individual time trial days or mountain hill climbs. You?ll be amazed at the rolling resistance -- or lack thereof -- you'll feel when you head out onto the road with the Ultremo TT tires. They use a harder compound rubber in the middle of the tread. Schwalbe accomplished this by reducing the distance between their filler particles, effectively creating a denser, more durable rubber compound. When you ride in a straight line, this means that the internal friction of the rubber has been reduced, and you'll go faster, easier. The rubber compound gets softer towards the shoulders of the tread for inspiring traction through fast corners. The casing, made from 300 tpi polyester, offers a road hugging feel. It's supple and flexible to conform to irregularities in the surface of the tarmac and to rebound. This helps make it faster than a lesser tire with a stiffer casing.The quality of the tire hinges on the quality of the production process. As the Ultremo TT Tubulars are all handmade, only the most reliable experts are given access to their construction process. And their success with equipping the best professional teams, including the '10 double Grand Tour winners Liquigas and the hot new team Leopard Trek, is appropriate testament to Schwalbe?s performance and reliability.The Schwalbe Ultremo TT Tubular Tire is available in a 700c x 22 in Black.
