The Effetto Mariposa Caffelatex Tubeless Valve is an essential upgrade for cyclists seeking a reliable, versatile solution for their tubeless wheel setups. Designed for durability and ease of use, these valves cater to riders across various disciplines who need a flexible, lightweight component that adapts to different rim profiles. While the modular design ensures broad compatibility, users should ensure the conic adapters are correctly seated during initial installation to maintain a perfect airtight seal.

Yes, the included conic adapter allows the valve to seat correctly in both Presta and Schrader-drilled rim holes.
Use the slotted end of the provided aluminum valve cap as a tool to unscrew the core from the valve stem.
Yes, the removable core design is compatible with standard tubeless-specific valve extensions.
No, you should only tighten the valve nut by hand to prevent damaging the rim or stripping the threads of the valve stem.
The valves are constructed from a durable, lightweight aluminum alloy.
Check if the nut on the outside is tight and ensure the rubber conic adapter is not pinched or misaligned inside the rim.
Remove the valve core using the integrated tool in the cap and clear any dried sealant blockage from the stem using a thin wire or pick.
To install, slide the valve stem through the rim hole and ensure the rubber conic adapter is seated firmly against the interior wall of the rim. Slide the O-ring and nut onto the exterior of the valve stem, tightening by hand until the base is secure. Do not overtighten, as this can damage the rubber seal or the rim tape.
Compatibility: These valves are designed to work with both standard Presta and Schrader-drilled rims. The system is also fully compatible with standard tubeless valve extensions if you are running deep-section aerodynamic wheels.
Care: Periodically remove the valve core to clear any dried sealant buildup. If you notice a slow leak, ensure the valve nut is snug and check that the core is properly tightened. Replace the O-ring if it shows signs of cracking or hardening due to chemical exposure from certain sealants.
