It's not about going tubeless for the sake of eliminating tubes. It's all about the countless benefits of going TUbliss® that makes every rider and racer better, faster, and more in control. TUbliss® is, essentially, a high pressure rim lock and seal that secures the entire tire bead to the rim, completely eliminating the use of a conventional tube. TUbliss® allows you to run a low tire pressure (as low as 10 PSI) which dramatically improves traction; especially important for Enduro and Baja racing. Since there's no conventional tube, the days of pinched tubes and flats are over! Even if you get a tire puncture, the bead stays seated to the rim. A high pressure rim lock and seal that secures the entire tire bead to the rim. Allows you to run a low tire pressure (as low as 10 PSI).
