What are the lighest valves for tubeless?

[Liggero]

I plan to remove inner tubes on my mtb this summer and finally install a latex tubeless system. I have a notubes rims and schwalbe tires so it should work with no issues. But I was wondering, which are the lightest valves around? I guess some are made of steel and I saw some made of aluminium, made by american classic i think. wht options do I have? which one do you recommend? are the ones of aluminium good enought? thanks a lot.

I went with the alu ones from american classic. They seal good and have a removeable core, I don't see why not go for these. Light as well, 7 gms for the pair.

these are much better than american classic for rims with the inner part not flat, like the notubes alpine i use.

i was gonna mention the American Classics as well, but it looks like we have a new winner!

I'm waiting to receive them. I'll let you know how they perform.

it looks like they might be 4.8g each. If so, they'd be heavier than the AC valves.

I have the american classic valves, they are pretty good..

Those 4.8 gr each, the price is for one or the pair?

Cheers

Speaking of valves for tubeless applications....

Where is the cheapest online store I can buy several of these? (They don't have to be the lightest but I want them real cheap!)

weight of these might be heavier than american classic ones, but the american classic only work on rims with a flat area inside. these ones work well on rims witha profile shape inside, like notubes rims. price is for teh pair. I got mine already but won't be able to install latex until july.

amclassics work on all the rims ive tried, including rovals and notubes. the o-ring they use as the base is tall and squishy, its had no problems conforming to the rim shape.
