Effetto Mariposa Tubeless Valves (40mm)-Silver (2 Pcs)

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-tightness, 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.

Generally speaking, the conic adapter makes life a lot easier with the various rim profiles, as in some cases a flat-base works better than a conic base, 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 aluminum alloy that will bend before breaking, adding reliability to the lightness required by modern rims.

Great look:
Effetto Mariposa valves come with a red-anodized aluminum cap, to underline their quality and make them easily recognizable even when mounted.

Removable valve core:
This feature allows easy mechanism replacement and the fitting of our tubeless-specific Caffélatex Valve Extensions.

Available sizes:

• 40 mm length for rim profiles between 10 and 30 mm
• 70 mm length for rim profiles between 31 and 60 mm
• 100 mm length for rim profiles between 61 and 90 mm

Complete with accessories:
Each pack includes two Caffélatex Tubeless Valves, two red-anodized aluminum caps, two rubber conic adapters, two nuts, two o-rings and a Presta mechanism/valve extension key.
