You asked.

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.  

Anything else?

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.

FAQs

How are tubeless valve stems measured- and which one will fit my rims?

Valve stems are generally measured from the end of the base to the end of the stem (not including the valve core).  Does that make sense?  No!  But it's how things are done (and we don't make the rules).  We've included a photo above for reference.  Now for the fun part: rim depth measurements go to the end of bead hook so don't correlate directly to the valve stem length needed.  For example: on a 38mm deep rim the distance from the tire bed is usually closer to 30mm. 
 
Our 44mm valve stems are generally appropriate for double-wall rims with a nominal depth up to about 35mm- but unusually short bead hooks or deep center chanels can push things a couple of milimeters up or down from there.  Your best bet is to measure the distance between the center chanel of the rim and outer wall using the stick at the end of a set of calipers or by inserting and marking a straw, toothpick, or similar.  The nominal valve stem length should be at least 15mm greater than the dimension you come up with.
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.
