PRESS RELEASE: e*thirteenSlow tubeless leaks can come from a number of causes, kill confidence, and can give riders "flat-tire anxiety" the whole time out there. Old sealant dries out and needs to have a fresh dose after a while, but that leaves a nasty mess and creates additional risks from breaking the tire bead – and it might not seal properly anyway. We all know if you spill and let it dry, it might as well be permanent.
All this more often than not, results in riders opting to "wing it" until encountering a real problem that can’t be ignored. Adding sealant through the valve body gums up the valves which are hard to clean and can cause a mess. This results in many riders opting to partially remove the tire to add sealant which takes more time. Removing the tire to refresh old sealant this way can compromise bead seat sealing.
Servicing tubeless is now significantly improved with our newly designed Quick Fill Plasma Valve. The two-piece valve body and stem is oversized for higher air and sealant flow, and requires no tools. The lower valve body is large enough for the sealant bottle nozzle to fit directly inside, resulting in zero mess installs and refreshes.
Aaron Gwin and the Intense Factory Racing mechanic John Hall install e*thirteen's Quick Fill Plasma Valve.Valve Features:- Large diameter valve body for high air flow and clog resistance.
- Tool-free disassembly and assembly for easy installation and maintenance.
- Full CNC construction for durability and corrosion resistance.
- Offered in two lengths to fit the full range of rim depths.
- Grooved base for compatibility with tire inserts.
- Available now in three anodized colors - Black, Naranja, Eggplant.
- Bronze and Intergalactic colors offered soon.
Valve Benefits:- Throw on new tires without adding sealant until after mounted.
- Add sealant to existing tires that need a refresh without breaking the bead.
- Sealant bottle nozzle plugs right into the valve body for zero mess.
- Valve body can be removed without tools for ultra fast deflation.
- Valve core less likely to gum up with large flow body.
- Valve core and body are easy to remove and clean without removing wheel and/or tire.
- Less tubeless stress means longer, and more enjoyable rides.

I do all that with regular valve stems.
By the way I have titanium valves that weigh 0.1 grams less and enable you to pump up your tires. It is also possible to pout sealant into the tires through these new valves too. I am selling them for $279 (they are 3d printed). Sorry, they only come in one color.
Keep in mind that they will be able to do all of the things that you claim to be able to do with your existing valves.
The only tubeless valve the LBS had otherwise never would have ponied up that much money. And no color anodizing !
Trading out the ability to unthread the valve core for double the bore size was brilliant. It's ridiculous how much air gets in there compared to my previous valves that I was so impressed with...which were E13 lol.
The basic sealing mechanism is exactly the same concept as a presta just with the seal moved to a more advantageous location. And the design eliminates the jam nut, the removable core threads, and the removable core seal. That’s called a “simplification” in case you were wondering.
The only thing is that you cant inject sealent through the valve with cushcore, because there isn’t enough pressure against the insert.
On the front I can inject sealent through the valve with just a minor tiny bit that goes out the side.
Best things ever!
My interpretation inside the mind of early and current tubeless engineers, designers and product managers:
"Hey we came up with this cool liquid that allows the tires to seal and you can stop using tubes."
"Rad, how do you get it in the tire?"
"Pour it in before you seed the bead. It's a bit messy, but we're still thinking about that.."
"Hey what if you inject it through the valve core?"
"you mean that tiny presta valve that all hardcore cyclist are obsessed with? You know a lot of riders think shrader valves are for rental bikes only."
"No what if we designed a better Shrader valve? Both for more reliable and better purpose functionality..."
"SHHHHUuTT your mouth! that's for 20 years from now when we run out of geo and suspension upgrades. Now is the time to get presta valves caked with latex kidney stones so people go nuts and have to buy $30+ new valves... they will look sleek, all the local shop techs will have a task to take up half their day and we can sell the crap out of this goop that will spill and dry left and right"
"Are you sure that's the best solu.." [Punched] [knocked out] [silenced]
At least this new product offering is in the same price range as the current, rather than some ridiculous $80 for tire valves
But...
"Why don't manufactures stick with one standard!"
Manufacturers stick to one standard.
"Why the f*ck aren't we changing standards!"

As for valve length, I've never had issues actually but it largely depends on the rim. The age of super high profile rims seems to be over and most seem low and wide, so that should work just fine.
I wasn’t trying to make any particular point, and am not personally offended by valves of any identity, simply stating there are in fact benefits and drawbacks to everything and life. Pick a valve and be a dick about it.
Let's take a rim for example with an O/D of 35mm. I would say that's a good average for what's current on the market today for most mountainbikes (I understand this depends on discipline)
Now let's compare the diameter of bothe a presta (6mm) and a Schrader (8mm).
This is a difference of 2mm or 28.57%.
For sake of keeping it simple we will assume a valve hole for a Schrader is 8mm, however in reality, that hole would need to be oversized to accept changes in manufacturing tolerances and ease of installation
So a 35mm rim with an 8mm hole will have 22% of the material removed which would require reinforcement in order to compensate for the loss of material in that area. Reinforcing is not done however with alloy rims in most cases as alloy rims are generally extruded, and reinforcing would add more cost to manufacturing. The result is a weak point in the rim.
That same rim with a presta valve at 6mm would see a reduction of 17% of material at that location.
That's a difference of 5%.
Might not sound like much, but in an industry of incremental advancements, I'd say it's significant enough to say of the two available options, from an engineering standpoint, the presta is favorable. The solution is to improve the valves, and proceed with advancing the technology in order to provide more reliable and intuitive products to the consumer. I don't think sticking with technology that is more than a century old is the solution for anything.
The challenge is getting industry buy in. Companies like sram are making an effort with ideas like the UDH which creates alternative possibilities to further evolve what's currently available on the market today.
Sorry, that was a long winded reply. It's partially directed at the mindset of "choose a standard and be a dick about it".
Like, I get it, they want to promote it... but, umm no, I really don't want to watch two guys one valve.
I am still running a 2015 27.5 TRS+ rear wheel and hub that still works fine. Currently on 3rd cassette and derailleur.
I didn't ride enough to replace tires after one season, they prob have another season life in them. So I will just add whatever amount of sealant is needed without taking the tire off at all.
My DH rig gets a new rear tire every year... it's even easier. Why are you all struggling? Because marketing dept told you so?
Still don't struggle adding sealant.
Why add such complexity to something that already has a solution - remove the valve core...? Is there a benefit to this that I am not seeing?
Done!
But you can already do that with a regular presta valve.
I was under the impression the natural attempt of air escaping propagated the sealant into the needed volumes/crevices.
