Opinions, plz.
Best tubeless valve stems?

i've had no problems with stans. have a set from black ox right now and don't really like the way that they thread on-i always feel like the retaining nut is going to come loose.
people do seem to like the new higher flow ones ... i could see trying the i9s as they're not too spendy and i9 generally makes quality things. plus they're local-ish.

Cushcore valves are nice, haven't had one clog or leak on me yet. The Santa Cruz Reserve valves are supposed to be the bees knees but are rather pricey.
Just pick one that can have a good seal with the rim's center channel, the rest is marketing.
I have to use unblockable (sideways) valves as all my tires that are setup tubeless use inserts. So far I haven't had any issues with the rimpact or cushcore valves.
Which works with an air compressor, but then that becomes necessary equipment to own a bike? That’s ridiculous, it shouldn’t come to that. I’ve got the charger style bontrager pump that can’t move enough air to work specifically because of valve restriction. Therefore, it’s actually easier for me to use a regular HV floor pump, as in if it won’t fill with that, it damn sure won’t fill with the air tank thing and all that does is run out of air. 99% of pumps aren’t designed to work without the core.

I don’t know of anything that can really clean out latex (without melting skin or something). You can sometimes get some strings/pieces out, but it just gets worse over time. It takes a while, but cores become a wear item and eventually the stem gets too restricted in my experience.
It's interesting. I have had the same stems in the Tracer since May of 2015, some no-name blue presta stems, non-removable core. I was careful to always have the valve down when inflating, measuring, or adjusting air pressure.
They never gave me problems until after December '21 when I had a local shop replace the rear tire. Now the rear valve is gunked up with sealant and hard to open or close.
I just took the tire off to true the wheel, and the amount of sealant that they put in is large, whereas I have always been a minimalist.

I like it when I can’t hear anything and me and at least one buddy are covered in tubeless milk. That’s when I know the valve is working but the tire or rim are done. It’s a form of trouble shooting….
I've got a Topeak pump which has the built in air chamber that you fill to 160psi to blow the tire on with, it seems to always work.
If the tire beads are juicy with sealant sometimes all I need to do is pump up the tire in normal mode to seat it.
This guy... feels a little sketch pumping it to 160psi, but it works..
I have some of the 76 designs high flow valves. They work nice, just suggest a pump with a locking chuck on it.
I have both the gucci aluminum american classic/generic ones as well as stainless $5 ones. The stainless seem to be better. They spin less and are less susceptible to junk.
i'd be curious to see a head to head comparison between those and the reserve ones. especially since the 76d ones are claimed to be insert compatible. and less expensive
been using the I9 ones for a bit. they don't clog up nearly as badly/quickly as some others (stan's) i've used, and are easy to clean out when they do get gunked up.
if buying a whole new setup would probably try those fillmore valves.

I've been using the Filmores since Christmas. The air flow through them is (as-advertised) MUCH higher than standard valves. It's like removing the core. I have no issues running them with inserts either. The only knocks, aside from price, are that you have to add sealant directly into the tire rather than through the valve, and that over time I had some sealant build up on the tip of the plunger, causing a slow leak of pressure. (A little bit of hardened sealant was keeping the plunger from seating fully on the end of the body. But it was no big deal to clear off - popped 1 bead, lifted up the insert, and just rubbed the edge of the plunger to remove the goobers.)
You like it?
Either we have different definitions of the word "like" or you are a masochist. Do you "Like" when it gets in your eye? Is that fun? Lol
Yeah! It’s not polite.
Depends if someone giggles. That’s usually a good metric.
This topic is relevant to my interests. The generic looking stems I have on my Turner (Stan's I believe) keeps getting clogged up and won't let air out, and barely in. No inserts to obstruct it either.
Same stems on the hardtail have been solid since I set them up years ago.
No name Amazon stems in fancy colors on the Capra constantly leak from the seals. Does have cross drilled holes and has inserts but filling or airing down has not been an issue.
Muc-off stems on the Izzo sealed up first time and have not had any issues but that's only been three or four months.
At this point I'm leaning towards Muc-off if I continue to have the same luck long-term with these, and will likely switch the rest of them at some point. Though these Fillmore have me intrigued as well.

ooh how do you like that izzo? That's been on my list, not that I have new-bike-money anytime soon
Had my first odd thing with the Fillmore tonight. It was dusk (and I wasn’t wearing my glasses, shame on me). I added some air, that was easy. But putting the cap back on the valve got a teensy bit cockeyed, and either cross threaded a tiny bit on the valve, or inside the cap (I’ll investigate tomorrow). It worked just fine without the cap, though, so that’s good.
I am also going to paint the valve cap safety orange or something, way too easy to lose track of it while pumping.
Also concerned about topping off sealant, they claim any injector will work, but those are a PITA compared to the used small Stan’s bottle method.
Also curious how one would ‘degunk’ the valve of built up sealant (we all know it’s gonna happen).

Dissolving Dried Latex with Commerical Products
There are several commercial products that can dissolve Latex. "Goof Off" and "Oops", intended for household use, are found in many hardware stores and offer water-based and environmentally friendly versions. Tetrahydrofuran (THF) readily dissolves latex. Due to its highly flammable and explosive nature, THF is reserved for industrial use. Nitrile or neoprene rubber gloves should be used to administer THF..
Sounds…potent
