been a long time since I've had to buy any I think I'm some of the original mavic ust valves from when tubeless first came out. They've worked fine, but on getting my bike ready for summer I've noticed half the valve on the back has snapped off, but somehow it's still holding pressure, but I cannot too up.
anyway, must be loads out there now, what's the go to reliable easy to use valve?
Milkit
Those milkits look great. I use presta valves cut from tubes. Coninental do one with a removable core, you can get the thin shite road tubes for £3 on crc. Way cheaper than a "tubeless" valve, and you end up with a long bit of rubber for tying stuff up with.
Those early mavic UST ones were bad for the locknut siezing - stranded a few folk out on the moors who lacked a pair of pliers on their multi-tools.
Cut-out valves from an old inner tube are fine for tubeless IME. I have them on a couple of my bikes and haven't noticed a difference - if I'm buying a new wheelset then I usually will spec a pair of valves, because it's a v small cost, but doubt there's any real need.
I run the 8 quid a pair ones from eBay / planet X. All work fine and dandy with removable cores. No issues at all.

I just bought some of the cheap eBay ones - in a pack of 4.
+1 for milkit, just makes life easier and once you have the kit you only need valves to convert other bikes
milkit looks interesting. bit steep though. might be worth it if I was to go tubeless on the road bike as well.
is road worth a tubeless conversion? archetypes on 4seasons if that makes any difference
I'll need some tubeless stuff very soon, those milkit valves are a great idea, but £48 for the valves and a syringe!! :0
And I'm guessing due to the seal in the valve you can't use an injector that pushes on to the valve like you get with the orange seal endurance sealant? If you just wanted the valves on their own.
With the Milkit syringe you can use any old tubeless valve. The only difference is that you won't be able to keep the pressure in the tyre while checking/adding liquid which is nice but not that important if the tyres are a tight fit and stay fitted once pumped up once
is road worth a tubeless conversion?
Be aware that depending on the rim you might not be able to get up to the pressure that you want once tubeless
I meant if you just bought the milkit valves, they have a seal in the bottom which prevents sealant getting into the valve core, and also holds the pressure - if you used a standard tube filler like a stans or orange which fits over the valve, you not only leave the valve full of sealant but probably wouldn't be able to get the sealant past the valve seal if their was pressure in the tyre. Meaning you basically have to buy their injector syringe if you want to use their valves to the full potential. I see little point in buying their valves and adding sealant the old way with a cup.
As with most Swiss things, it's an awesome idea and works well, but is also bloody expensive. Also the same as most Swiss things! 🙂
American classic are probably the best but they only come in red. Bontrager valves are also pretty good. I use them but change the oring on it for a heavier duty one. These are silver.
Bontrager are £4 each American classic are £12 ish for 2 (ebay)
Seems like there's one major flaw in the Milkit system...
With the injector in the valve, when you turn the valve on the syringe, if you're not holding onto the plunger you'll be either losing a lot of air, or getting sprayed with sealant. 😀
....which is why when you buy them there's a big sticker on the plunger telling you to have no more than 22 psi in the tyre.
Having a bit of pressure in there pushes the sealant up into the syringe without you having to suck it out you just turn the tap and it all happens automatically.
My favourite bit is that you can remove the valve cores to mount a stubborn tyre but you don't lose the air when you remove the pump, you can put the core in at your leisure without the air gushing out and getting sprayed with sealant as you rush to get the core back in before the tyre pops back off. (I'm aware not all tyres do this but the ones that do are a pain in the rear)
fitted the milkit valves over the weekend. pretty impressed. only downside I found was I could break the valves seal by tightening the valve core. as soon as I worked it out easy solve by retightening the lock ring.
Milkit valves are the best. Can't believe there are people complaining about the price - compared to our / your several grand bikes a few extra quid for a valve is well worth it!
Depends on the rim, I've found with certain rims and certain tubeless valves they don't quite sit right and leak sealant through.
Advantages
Install tubeless tires easily and without a mess: add sealant after tire is fully installed.
I can do that anyway ... I just need a spoke key that fits a valve core.. (or a free <i>remover with a set of 4 new cores)</i>
Measure and refill sealant without having to release air from the tire.
I can measure it without releasing air ... then I release air and inject it with a £3 syringe if the tires are stubborn to get off ... or I can pop the seal and pour some in ...
Valves don't get clogged by sealant anymore.
Hmmm... is it a major hardship buying 4 for £2.50.... stick a new one in and wash the old one... if you bend any chuck away and replace.

Yep ...
