Everyone knows red is the fastest color.
Scott opted to use American Classis tubeless valves. They've got some cool features. My personal favorite part is the small plastic spacer - it keeps the nut up off the rim so it's easier to tighten, and the spacer matches the shape of the Stan's rims perfectly.
The spacer is a nice touch.
The only thing I'm not crazy about is the way they seal against the rim - they have a metal backing with an o-ring. The metal backing will ensure you can't pull them through the rim, which is cool.
Cool detail you'll never see.
But, the o-ring is flat, and it has to seal against a curved surface, so you have to tighten it down enough to squeeze in. It does work, I'm just not sure about the longevity with that o-ring being so compressed. Time will tell. The red anodizing matches the nipples perfectly, and at ~3g a piece they're very light.
The o-ring doesn't match the curve of the rim perfectly, but can be tightened down enough to seal up.
Ready to ride!
