Trek Factory XC Race Team’s go-to tire is lightweight, fast-rolling, and built with confident traction to fuel all-out efforts.
Built to race—and win
The XR1 Team Issue TLR is an ultra-fast, ultra-light cross country race tire that's ideal for rides where speed and acceleration are key. The smooth center tread makes it easy to maintain speed and a more aggressive side tread adds confidence for corners and techier sections. The TM-Speed rubber compound rolls faster and Bontrager's Inner Strength construction delivers lightweight protection against tread punctures.
