Perfect fit on my Giant Trance.Expensive, but you can feel the quality.Highly recommend, but in my experience like all valves, if you inject sealant through them, they will block.Partially take the tyre off to place sealant.

Ich habe an zwei MTBs, allesamt mit Newmen Evolution Felgen, auf tubeless umgerüstet. Einen Satz mit einem Umrüstkit von Milk it --> alles easy, sofort dicht.Mit diesem Set danach ging das Vorderrad gerade noch so, Langzeitdichtigkeit muss sich noch zu zeigen. Hinterrad habe ich dreimal gemacht - inkl. neues Felgenband. Das Problem war stets der Ventilschaft an der Felge. Letzterer Versuch mit einem Stückchen altem Schlauch über dem Ventil, das scheint nun zumindest soweit zu halten, dass es über Nacht hält, jetzt vielleicht nochmal frische Dichtmilch nachfüllen. Es ist ein besonderer Spaß, das Auf- und Abziehen einer Big Betty Super Gravity...

In converting a DT Swiss wheel set to tubeless I was using DT Swiss stems.I nearly got stranded on longer gravel rides a couple of times with a leak at the valve stem. This is the kiss of death for a tubeless setup. I nursed her home each time and went back to the drawing board. I finally realized that it was the stem and not the tape job, sealant, etc. I ordered these Stans stems and no more issues in ~300 or so miles so far.

These 35mm stems are shorter and lighter.

I installed these on Sun Ringle fat tire rims. So far these are sealing well. No issues with installation and the removable valve seal allows for sealant injection. There are lots of fancier looking stems out there, these are utilitarian black.

This set was the perfect length for my 25mm bed deep wheelset. They're secure and did not leak. They seem to be well made. I was concerned with not having a seal on the outside of the wheel, but the round bung flattens and does the job internally. I love the stealthy black look.
