Caffelatex Tubeless Valve is a great accessory for any tubeless wheel. With its modular base, this quality tubeless valve easily adapts to any rim. Available in 40, 70 and 100mm lengths, black or silver Adaptable to any rim profile thanks to the provided conic adapter, Caffelatex Tubeless Valve works on both Presta and Schrader-drilled rims: on Presta-drilled rims (valve hole diameter: 6,5 mm): depending on the rim shape the flat rubber valve base might ensure a perfect air-tight fit, without any additional adapter, or the conic adapter might be needed. on Presta-drilled with a wider (> 6,5 mm) inside hole, or when used on Schrader drilled rims (valve hole diameter: 8,5 mm): we recommend fitting the conic adapter on the valve before inserting it into the rim. With an incredible variety of rim profiles in the market, in some cases a flat-base tubeless valve works better than a conic base one, and vice-versa. With Effetto Mariposa valves, the conic adapter allows to pass from flat to conic in a breeze. Light and reliable We opted for an aluminium alloy that will bend before breaking, adding reliability to the lightness required by modern rims.
