Tubeless Valves

[JBV]

Is there a "best" tubeless valve for road rims, or it it rim specific? I've used Stans & American Classic, the former wear out pretty quickly, the latter seem to require a ton of tightening to seal up. Used a DT yesterday (on a Pacenti rim) and it seemed decent. Are there other experiences or recommendations?

I've been running tubeless for quite some time now and have had the best luck with Shimano, Hutchinson, and Easton tubeless valve stems. Actually, I can say that I've never had one fail. I did however have a Reynolds 60mm valve stem fail on a set of Tubeless Assaults when I over tightened one trying to seal a leak.

I would recommend that you stick with valves with replaceable cores. It improves tubeless significantly to use a sealant, which works much better if you can shoot it straight in the tire through a valve stem with the core removed. I have had good luck with the Stans product and Vittoria cores.

Where is it not sealing up? Is it the core or the base?

The base. Maybe I'll take a picture of the chewed up Stans valve. The DT I replaced it with seems to be working well so far. I use American Classics on another 2 sets of wheels and they seem to work OK.

I'm sorry, from the responses I apparently assumed some things were self-evident. I use sealant and removeable-core stems, and I know how to tighten the cores when I put them back in. I guess I was hoping others had experienced some of the wear and sealing issues I had, and there was a valve that addressed them.

I really don't want to test every different tubeless valve on the market myself, but that may wind up happening. I can see why road tubeless is so slow to gain acceptance, despite its other advantages. The average consumer/rider wants a plug & play setup.

i would like to recommend using pipe-sealing tape between core valves....

Thank you for this recommendation, I should have clarified the leaking was from the base of the valve stem, the rubber grommet not sealing up properly against the rim. The valve core is fine.

Are you finishing the valve hole on the rim?
Just taking the edge off with a small file pays dividends.

I'll give that a try, thanks.

The best valves I used while riding tubeless road were Orange Seal valves. They come with rubber o-rings to prevent damage to the rim (and also allows you to tighten the valve more, preventing sealant from leaking).

i noticed that schwalbe valves also come with o-rings.
Dumb question but does the o-ring go between the locknut and the rim, or inside the rim?

edit: a quick google turned up the answer
