The first name in tubeless

Stan's lightweight alloy valve stems are half the weight of standard brass valves, weighing only 8g, 9g or 10g per valve respectively for the 35mm, 44mm and 55mm models. The secure round base is compatible with most tubeless rims and is a perfect fit for all Stan’s BST and BST-R rims. With an array of colors to choose from you can mix and match your ride.
