Race Ready

Light-weight for quick accelerations and efficient climbing, XR1 features a tread and compound that rolls faster, making it the go-to race tire for Trek Factory racers on the fastest World Cup courses.

Inner Strength

Our Inner Strength Casing is made of a lightweight nylon insert that provide strong, supple sidewall protection for added tire durability without a weight penalty.

Fast Rolling Tread

XR1 Features a smooth center tread that accelerates quickly and easily maintains speed. The more aggressive side knobs add grip and confidence for cornering and through more technical sections.

TM-Speed compound

Our proprietary TM-Speed compound is designed to roll faster without sacrificing traction. 120 TPI construction keeps it lightweight and fast, with a great tire feel.

Tubeless ready

A properly set up tubeless system lets you run lower tire pressure for better traction, added confidence, and a smoother, faster ride.
