Terske Blue Anodized Aluminum Tubeless Valve Stems


SKU: TAH1TE98999


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?

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.
