Tubeless Ready (TR) technology is the latest innovation from Keith Bontrager's garage. Designed to improve upon existing tubeless systems, Tubeless Ready tires offer a secure bead to rim interface like standard tubeless tires, but are 100 grams lighter per tire. They work in conjunction with sealant to provide a lightweight seal and flat protection that significantly improves performance.

If you look at the spoke bed of a low-profile Bontrager rear road wheel (like the Race X Lite or Race Lite), you'll notice that the spokes don't join the rim at the center. Rather, they're shifted slightly toward the non-drive side. Bontrager calls this design feature OSB, or Offset Spoke Bed. And here's why we do it.
