Built to last: Terske black titanium tubeless valve stems with oil slick highlights. Durable, serviceable, and lightweight. (Not to mention pretty darn good looking.)
One Gram Heavier.
Why titanium for tubeless valve stems? While we love the sort of upgrades that shave weight and add a bit of character to our builds, sometimes those upgrades come with downsides. In the case of lightweight aluminum tubless valve stems, that weight savings comes with a serious reduction in strength- as anyone who has snapped a valve stem while frantically pumping mid-race (or hanging their bike from a hook in the garage) will attest.
So we propose a compromise: give us back a gram and we'll give you a tubless valve stem nearly four times as strong as the alternative.
Seeing as Ti is more expensive to source and slower to machine than aluminum, 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 to begin with, as soon as you've replaced your first gasket you've come out ahead. And let's be honest: the last thing anyone needs is another disposable product.
Two valves and four sets of spare cores and gaskets costs $47.45, a little less the $16/set going rate for non-serviceable brass tubeless valve sets.
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.

We actually use aluminum for the knurled nuts because Ti there was adding cost without adding value. It also gave us the opportunity to offer highlights in colors that aren't readily achievable in Ti. The replaceable valve cores are brass and the gaskets -of course- rubber.
Well, if you're anything like us those dust caps are the first thing to go- if not lost on the trail then set aside after the fiftieth (or fifth) tire pressure check. So we include dust caps to protect the valve stems in transit and in case you want to use them- but it won't hurt our feelings if we don't see them on the bike.
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.

CushCore Tubeless Air Valves are specially designed to work with a CushCore insert. The air passageway is T-shaped, rather than a simple through-hole, which prevents the insert from obstructing air flow through the valve. The valve body is CNC machined from 6061 T-6 anodized aluminum, with a tapered rubber collar permanently bonded at the sealing interface. The valve core can be removed to add tire sealant.
