About Stans NoTubes:
Before anyone in the industry even thought to consider the concept, Stan extended his tubeless system brand to encompass tubeless rims with short side walls and his patented bead socket technology. Utilizing the same ingenuity that helped him develop the tubeless system, he has devised a line of tubeless ready rims that maximizes strengths and minimizes weaknesses. Bead socket technology allows for lower sidewall heights, increasing tire traction and decreasing the chance of pinch flats. All Stans rims have something in common that sets them apart from all the others, exceptional and innovative design.
