Specialized's Fast Trak Armadillo Elite 2Bliss Tire offers an ideal combination of traction, weight and flat resistance. Its dual-density rubber compound mixes a fast center tread with soft shoulders and short knobs for low rolling resistance and confidence-inspiring cornering. What's more, the Fast Trak features Specialized's Armadillo and 2Bliss technologies for a knockout combo of pinch-flat and puncture protection.
Armadillo Elite is Specialized's toughest all-around puncture protection for 4-season high-mileage riding. It provides superior puncture resistance in a lightweight package with a folding tire bead. A Kevlar cap-ply (see image, light blue) protects the sidewalls and provides bead-to-bead puncture protection, plus an additional nylon belt (see image, red) under the tread increases durability where the tire contacts the ground.
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.
