Description

Four times as strong. One gram heavier

Seeking to build a stronger counterpoint to increasingly common lightweight, aluminium tubeless valves – Lindarets found that their first samples of titanium valves proved to take at least four times the force of aluminium valves to bend on the test rig.

Combining some cleverness to reduce sealant clogging and improve airflow, Bead Shed Technology (pat. pending) to assist tyre beads to not get hung up on the valve during installation and available replacement wear components – Terske Tubeless Valves were born.

Titanium is expensive, but will likely outlast one or more sets of wheels – saving money in the long run.

Features

  • 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 44mm stem (5.3g with dust cap) / 6.25g per 60mm stem (6.5g with dust cap)

FAQS

Is the whole tubeless valve stem titanium?

We actually use aluminium for the knurled nuts because Ti there was adding cost without adding value.  It also gave us the opportunity to offer highlights in colours that aren’t readily achievable in Ti.  The replaceable valve cores are brass and the gaskets -of course- rubber.

What’s with the plastic valve cap?

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.

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 centre channels can push things a couple of millimetres up or down from there.

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 check them out here
