Terske Aluminum Tubeless Valve Stems
Aluminium presta tubeless valves featuring:
- More airflow
- Less sealant clogging
- Bead Shed Technology
- Available spares to rebuild
Terske tried to oil slick anodise their Titanium Tubeless Valves but the results were less than they expected from a premium product.
So, they did the next best thing, and built an aluminium version, titanium nitride coated it and voila, shiny, oil slick-y tubeless valves.
- Bead Shed Technology (patent pending geometry) to assist the tyre bead to slide over the valve stem on installation.
- 86% larger thru hole internal diameter than regular valves and reduced places for sealant to clog
- Rebuild-able with readily available replacement parts kits – bundle available above
- Weight: 5g per stem (5.5g with dust cap)

So they’re not titanium?
No- just coated with it. The aluminium will need a bit more care than our Ti valve stems, but if you’re reasonably gentle when using a hand pump and don’t hang your bike by the valve stem you should be alright.
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.
Your best bet is to measure the distance between the centre channel 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 you speak of?
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.
