You asked, we built them. Why aluminum tubeless valve stems? Well, it turns out that oil slick anodizing on our titanium valve stems just didn't come out as well as we -or you- would have liked. So we did the next best thing: made our own custom aluminum valve stems and coated them with titanium nitride. Seriously. Much like the gold TiN coating on those fancy gold drill bits, this titanium nitride coating allowed us to anodize our valve stems in a sweet, sweet rainbow oil slick. 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.  Tech Specs Weight5.0g per stem5.5g with dust cap Package Quantity2 stems (one bike worth)
