Dual compound construction splits the tread into two distinct zones that each handle a different job. The center strip uses Gripton T2, which Specialized engineered by tuning polymer chain mechanics to reduce rolling resistance. The shoulders use Gripton T5, the same compound that's been delivering cornering grip in previous generations. This layout lets you carry speed on straightaways while maintaining traction when you lean the bike over.

The BlackBelt sits under the tread as a hybrid Kevlar breaker that stops sharp objects before they reach the casing. Specialized redesigned this layer to be lighter and more flexible than the previous version while delivering eight percent more puncture protection. The 120 TPI casing deforms around road imperfections rather than transmitting every bump through the contact patch, which improves both comfort and mechanical grip on rough pavement.

The tire works with both hooked and hookless rim designs, which matters if you're running newer carbon wheels that use hookless beads. Zylon reinforcement in the bead exceeds hookless burst pressure standards by two hundred percent, so the tire stays seated even when you're running lower pressures for comfort or traction. The 2Bliss Ready system means you can set it up tubeless with sealant that self-seals small punctures during rides.... Read More
