We built them.
Why aluminum tubeless valve stems? Well, it turns out that not everyone needs the added strength (or let's be honest, cost) of our titanium valve stems. So took much of what makes our Ti stems special and applied it to the lighter metal.
But why stop there?
Seeing as no one needs another disposable product, we wanted to keep our our tubless valve stems in service as long as possible. So we made the parts that wear or which can be fouled by sealant easily replaceable- and their replacements readily available. So while the cost more than brass to begin with, as soon as you've replaced your first gasket you've come out ahead.
Well there's our Bead Shed Technology- patent-pending geometry that helps to keep the tire bead from hanging up on the valve stem. It's a small thing, one that you won't notice working, but it does make tire installation and seating easier. After all: we just want to get you on your bike and riding as quickly as possible.
And finally, we moved obstructions from the valve stem body for an 86% larger thru hole than standard and fewer places for sealant to hide and congeal.
We want these tubeless valve stems to be as easy to install and maintain on as many tubeless wheels and tire setups as possible.

How are tubeless valve stems measured- and which one will fit my rims?
What is this Refresh Kit?
It's a spare set of valve cores (the assembly that actually closes off air flow) and gaskets (which create a seal between the valve stem and rim). Because it never hurts to be prepared, these ship in sets of four. We even include a small valve core removal tool. Add to your valve stem purchase above or find them here.
