The Grand Prix 4-Season is a reliable companion for training rides and in competition, come rain or shine, featuring superior durability that's ready for any season.

• Designed to wear longer and offer improved traction in harsh conditions and lower temperatures
• Vectran Breaker is spun from liquid crystal-polymer to create a multiple-thread thermoplastic yarn. This partially crystalline fabric is more cut-resistant than aramid and its tensile strength is five times higher than that of steel. A Vectran Breaker is lighter, more flexible and effective against cuts than a comparable nylon breaker, without affecting rolling resistance
• Duraskin provides a cut-resistant layer from bead to bead
