The new tubeless-ready S-Works Tracer is made for CX racing in dry and intermediate conditions and spec’d with a light and supple 120 TPI casing with grippy T7 GRIPTON® compound. This rubber grips in all course conditions and will give you confidence on every race lap. The new GRID RACE sidewall protection is a lightweight cross-woven polyamide mesh, which is tear- and puncture-resistant but still very elastic for a supple ride. GRID RACE provides the best combination of protection, low weight, and speed, all while maintaining a responsive feel. A strong bead holds to the rim at low tire pressures, and the tire cross-section is designed to meet the UCI rule of 33 mm on a wide modern rim shape.
