PRESTA ADAPTER RIM EXTERIOR, 160126-02

Purchased a mountain bike that came with rims — similar to the Alex 26-in G6000 — that used Schrader inner tube valves, which I wanted to convert to Presta. Although there are aluminum adapters available that would work, most are design for generally more wider and flat surface rims. So thought it would be great to design an adapter that would conform more to the shape of the rim and/or valve hole opening — to give the adapter a more finished appearance. In addition, what is really great about this adapter is that it also eliminates the galvanic corrosion between two dissimilar metals — like an aluminum adapter or rim and the presta valve nut.

Another advantage is that the adapter can be reused for another similar shaped rim or removed so that a Schrader valve inner tube can be used again!

From a more aesthetic perspective, it can be printed in a color that is similar to the rim or other bike components.

The overall diameter is .375” (3/8”) that tapers down to a .313” (5/16”) to fit a standard Schrader valve rim hole of 21/64" (0.328").
