Stan’s lightweight aluminum valve stems are the perfect upgrade for riders seeking to reduce rotational weight without compromising reliability. At nearly half the weight of standard brass valves, these high-performance stems weigh just 8g, 9g, or 10g each for the 35mm, 44mm, and 55mm versions respectively. Whether you're optimizing your setup for racing or simply want a lighter ride, these valves deliver noticeable savings in grams where it counts most.

The secure round base ensures a tight seal and wide compatibility, fitting most tubeless-ready rims and offering a perfect match for all Stan’s BST and BST-R rims. With a removable valve core, adding sealant is fast and easy, streamlining your tubeless maintenance routine. Designed to fit valve holes up to 8mm, these stems are as versatile as they are efficient.

Available in five vibrant colors—black, red, blue, green, and orange—Stan’s aluminum valve stems let you add a personal touch to your wheels while enhancing performance. Sold as a pair, they’re a simple yet impactful upgrade for any tubeless setup.
