Thanks to the provided conic adapter, Caffélatex Tubeless Valve works on both Presta and Schrader-drilled rims:
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.
We opted for an aluminum alloy that will bend before breaking, adding reliability to the lightness required by modern rims. Weight(*) is 3,6 g for 40 mm, 5,1 g for 70 and 6,5 g for 100 mm.
(*) valve alone without accessories.
Effetto Mariposa valves come either full black (black valve, black cap) or silver (silver valve, red cap). The aluminum cap functions as mechanism key.
This feature allows easy mechanism replacement and the fitting of our tubeless-specific Caffélatex Valve Extensions.
These, plus our 35 mm or 45 mm Caffélatex Valve Extensions, allow to fit virtually any rim in the market.
Each pack includes two Caffélatex Tubeless Valves, two anodized aluminum caps, two rubber conic adapters, two nuts, two o-rings.
Purchased specifically for shraeder drilled rim set up tubeless with this presta valve stem. Perfect fit, nice overlap, strong seal. Two weeks, 100 commuter miles, flawless.
Cheers.
