MilKit’s Innovative Valve is the Answer to All of Our Tubeless Problems

because popping your bead and looking inside the tire is too difficult?

Who puts the sealant in through the valve?
I have always just put one tire lever on to stretch the tire bead open enough to inject the sealant.
It is a lot easier.

Adding Stan’s through the valve is awesome simple. Pick up those little 2oz bottles with the tip so you can shoot it directly into the valve to refill. Just pull out the valve core and bam. No mess, takes 2 seconds. Not sure why anyone would deal with injectors, syringes, dripping stans onto your work bench, etc.

Until you can pull the Stan’s urchins/tumors out thru the valve, I don’t see how this is that helpful in the long run.

Interesting valve for sure, but as others have mentioned, popping your bead is really not a problem before you head out, and I don’t imagine you’d be taking this kit on the trail with you. In fact, the only mess I’ve made is when seating new tires with floor pump and the tires give me a hard time. For that, I got a WTB Flash Charger pump and the thing kills it!

I guess I’ll be the first post in favor. Adding sealant through the valve stem is much less hassle than popping a bead and partially unseating a tire. Especially when you’ve got a valve core removal tool. And I have many times had sealant clog the valve itself when air is being let out to decrease air pressure. This may solve that; however, it leads to my question. With what is basically a check valve being mounted on the interior end of the valve stem, how does one allow air pressure to escape the tire? Does depressing the valve core head open the check valve somehow? Seems like a neat system to prevent sealant clogging the valve core, but creating a new problem if air pressure can’t be carefully released from the tire.

How true

Seems like a creative way to make life easier. I wouldn’t say adding stan’s before was a problem but for a lot of people who don’t have air compressors it’s a pain to break the bead. I don’t think the convenience is quite worth the cost, but still a good idea.

Sealant is for anyone who lives near cactus, bull briar, prickly pears, thorns etc… Growing up where I did, flats and torn up shins from briar was a daily thing. Sealant, even just for tubes, was a godsend.

That said, if air can’t be bled from the tire without breaking the bead…I don’t get the point.

Just a short answer to some questions above:
– The valve core has an extension that pushes open the rubber flaps to release air
– There is a new kind of valve core tool included

@jlrichar Sealant is for anyone who wants lighter rims and tires. Aside from getting one set of Nobby Nics seated I’ve had great success with all the tubeless ready tires I’ve used.

Judging from their accents (and the IndieGogo website) they are from Switzerland. Student loans don’t exist there as high level education is free. So, great conspiracy theory you got there.

I want these just so I can complete my murdered out bike build with blacked out valve stems! 😛

Given how quickly we go through sealant here in the desert (death by a thousand papercuts- or something along those lines), I can see the appeal of the idea. I can’t count the number of times I’ve popped a tire off only to realize that two scoops’ worth of Stan’s had been put to use sealing hundreds of little cactus holes.

Maybe it’s not for everyone/everywhere, but it sure beats unseating a tire every week or two just to check or blindly adding sealant when none is needed.

I’m with Lindarets on this one. I think this is brilliant. I am going to their website to support this. I use a syringe now but the valve and its base is perfect.

If you don’t want to gum up your valve with sealant then always inflate, or bleed, with the valve at the 12 O’Clock position. Add sealant with the stem at the 3 O’clock or 9 O’clock position. You won’t gum up the works that way.

I guess with low pressure tires unseating a bead to check/add sealant isn’t a big deal, but on road bike tires it’s a pain in the ass to re-inflate after a bead has been popped.

Reading the comments it seems that not everybody has had a lot of varied experience with Tubeless tyre systems and that is fully understandable. Many combinations of rims and tyres and circumstances would see no major benefit from such a system to easily justify the on-cost. In my experience, however, there can be some VERY awkward tyre/rim combinations and/or circumstances. On one of my wheelset/tyre setups the fit is ludicrously tight. I have had numerous problems with them but I still want to run them. Problems include:- Very difficult to mount tyres and I don’t want to use too much force with tyre levers on carbon rims too often if it can be avoided to dismount/remount even part of the bead to check sealant. When ambient temperature is cold multipy that problem to impossible. When I first tried to pry the bead open just a little, on a day of cold ambient temperatures, I instead had to cut the tyre off. Nect problem: these rims do not have a proper UST channel to retain the bead and when they are left aside unused for a while they also deflate enough for the tyre bead to slip into the middle gutter of the rim. Doh. Anyway, when that happens the tight beads also have a tendency to drag the ‘tubeless’ sticky rim tape down into the central gutter with them, wreck the seal, and leave the wheels un-rideable until I’ve done an hour or two’s work to carefully clean every speck of rubber remnant off the rims and replace the tape. Grrr. I am not saying that these valves will solve my problems in all circumstances but they sure could help a lot. I can’t imagine me fitting them to other wheelsets but, hey you never know. Congratulations to the designers. I’m in.
