Riders and racers around the world rely on the tubeless technology Stan developed, and the sealant has been honoured as one of the most important innovations in the history of cycling. “The First Name in Tubeless” is more than just marketing to us. Everything they learned about sealing conventional rims for tubeless used led them to develop their own line of rims and wheel sets. Featuring a patented Bead Socket Technology, the rims and complete wheel sets are regarded as the easiest and most reliable made. For over a decade, Stans products have set entirely new standards for performance, created completely new categories, and redefined what others thought was possible.
