Designed by the legendary Ned Overend, Specialized's S-Works The Captain is perfect for shredding any cross-country course. Its dual compound tread features firm center knobs that are fast-rolling and soft side knobs for exceptional bite in the corners. Plus, with Specialized's 2Bliss technology, you can run these sweet tires at traction-enhancing low pressures.
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.
The high thread-per-inch casing let this tire conform to the road/trail for superior cornering and comfort.
