These tubeless valves are made of aluminium and are very light. In black-anodized they look very sleek on each rim. The conical valve base works universally and will fit in most rims. This is whether you are buying from Alison's Biciclette or not.
The Schwalbe Presta Valve Extension (SV) is an ideal upgrade for bicycle tires, enhancing pressure readings and fluid changes without the need for extra tools.
