Each knob on Specialized's Fast Trak Control Tire has been shaped with the help of finite element analysis for less rolling resistance, great cornering traction, and low weight. The closely spaced center knobs with ramped edges keep you cruising fast and the casing is tough for excellent durability and flat protection. 2Bliss Ready design means you can take full advantage of lower tire pressures and decreased chance of pinch flats.
Tubeless ready tires are compatible with both tubeless-ready and standard rims. When used on a tubeless-ready rim with a special tubeless rim strip or rim tape, valves and sealant (sold separately), the tire and rim form an airtight chamber, allowing the tire to be inflated without a tube. This lets you run lower pressure for optimum comfort and control without fear of pinch flats. When used with a standard rim, the tire can be mounted and inflated with a tube.
