16 x 1.5 wire bead Marathon Racer. A 235 gram tire that inflates up to 85psi.
The fastest Marathon ever. Again! Now even lighter. Now even faster. Pure skin side walls and the new Speedgrip compound have further reduced weight and rolling resistance. Everything is optimized for speed. Pure dynamics: the low weight is noticeable every time you pull away. A RaceGuard belt protects against punctures.
Note: Skin-sidewalls are fast but sensitive. Always be certain to check for correct air pressure.
