I prefer schrader as they are easier to use and you can get cooler vavle caps for them.
From a rim strength/fatigue life point presta are probably better as the smaller hole will result in less stress.
Would be intresting to know if that is why presta is used for mtb rims or if it is just a fashion thing.
These do look like a good idea though some of the claims are pretty bold
it’s claimed you won’t even need a tubeless inflator
Most of the time tubeless works really easy for me but every now and then I get an awkward tyre/rim combo that needs core out AND an inflator/compressor. Do these valves flow better than a coreless regular presta or will they occasionally make my life a little bit harder?
Also, this has rather pissed on 76Projects new valve launch https://76projects.com/collections/shop-other-accessories/products/hi-flow-no-clog-tubeless-valves
I'll never forget it, we were coming off High Street in the pouring rain it was freezing. There must have been something wrong with my pump or really cheap tubes as they just kept breaking off when I tried to release the pump head. My mates were in stitches as my wife had washed my backpack and not rinsed it properly. The more I pumped each tube up the more I foamed up. By the end I looked like I'd been in an Ibeza pool party. Switched to Schrader after that until 26 inch disappeared and new bikes come with Presta.
"The cost of progress" is a well known economic term and now we can quantify it. It's a £20 tyre valve.
So they bang on about how much better the air flow is compared to skinny Presta valves but have the mentioned anywhere how they compare to Schrader valves? They don’t gunk up, they inflate nice and easily, the ends don’t get bent and most importantly of all, the tip of the little bottles of Stan’s fit in the end so no spillage.

Edit: Little not litre, fair comment but they fit in a coreless presta fine too
I think these guys are a bit miffed if the attention SC are getting
Different design, but same aim and far cheaper
To help avoid clogging park your bike with the valves at the bottom of your wheel, that way the sealant doesn’t pool in the valve.
I must be doing it wrong. Zero issues with presta valves on multiple tubeless wheels. stans valve core remover takes the core out in seconds. A syringe from an old reverb bleed kit injects the sealant. Core back in and a few pumps with a Lezyne track pump has the tire seated and inflating. 1 tyre in 20 maybe a bit stubborn and I have to get the airshot out.

No, you are doing it right but I am doing it wrong because all my valves clog up and need a clean. But forty quid a pair, **** me!
**** me!
and the swear filter by the looks 😀

Pissed off that we hadn't publicised ours earlier after having them for months. The designs are quite different though.
76 Projects valves are virtually identical and £24.50
But yep still wish we’d settled on schrader.
This.
Interesting. Design looks easier to manufacture than that 76 projects one, and I can see how the valve stopper at the bottom would stop clogging. Although I too wonder how you insert sealant through them.
They come with a lifetime guarantee
Does this mean they'll replace them when they wear out (like the bearings) or is it a 'lifetime' of the valve warranty against manufacturing defects?
To be fair about cost, these will probably be standard on the reserves, so 1.5k wheelsets and so on, progression is always good, plus 40 quid isn't horrific these days when wheelsets are getting more expensive.

That's would be an interesting discussion to have - maybe start a thread just on that?

Or they've just got a load of interest out of it? Theirs are 'unavailable' to buy.
Who’s is unavailable to buy? 76 have 2 different colours and various sizes available
I’d clicked on “adaptor” which selected
“No colour”.
Clicking on a valve then says not available. (Have to select pink or black )
D’oh
According to the STW Facebook feed, this is the most discussed item of the week. (I though that the "favourite spaceship" thread was much more interesting). Still, the power of free advertising eh?
What injectors are recommended for Stan's Race sealant? Their own version states it is not suitable as the fibres clog the outlet.
I didn't realise I had a problem with the valves I have - but now I know, the solution is shrader tubeless (core comes out, just like on the car ones, which are tubeless of course)
I also know the solution is certainly not something which relies on a removable (aka lost) cap to hold the valve shaft shut!
Having had 2 rides on the last week where I've had a Presta valve not seat and need pumping up multiple times I can see the need.
Infact if they really work as claimed £40 seems fine. Not from the point of view of how much they should cost to make but how much better they could make my life. I'd say they would add more value to my life than £1500 wheels or a carbon bar

What tyre valves need this?
What tyre valves need this?
Ones that cost forty quid 😀 (yes I read it, yes they hold air without the cap but the cap appears to do the job of the threaded bit on a presta of holding the valve shut)
According to the article the valve's held shut by the air pressure. The cap seems to be just a cap?
I’m pretty sure the cap holds it shut to give an extra bit of security. Sorry, I probably didn’t actually read it here but in the Pinkbike comments where reservewheels were being really good at fielding questions/criticisms.
e.g. they said
The poppet doesn't 'need' the cap to work. Air pressure in tire would hold poppet closed. If you lose the cap, the valve still works to get you home. And, you can contact us and we'll get a new cap out to you.
I’d love to try some for six months to see if they are the last valves you ever need but that price is too much of a stinger
Fiddly tool for Schraeder? You can get it built into the valve cap.
Even carbon can be drilled.
Ah thanks Rubberbuccaneer, I stand corrected
presta love? now that’s niche! 😳

"Scott from Corvus Cycles compared the Fillmore with the first Cane Creek Threadless headset. Something that will change the tubeless valve across the entire bike industry. That’s a pretty bold prediction, but I agree that it is one of the best new innovations that we’ve seen in the last couple of years."
Plenty of other brands doing innovative things with valves well before this, Reserve are just the first one to do it with the full weight of Santa Cruz's marketing budget behind it.
what's the deal, however, with these and inserts? I wonder if my rimpacts would prevent the valve from opening??
DrP
@DrP your inserts may have a slight impact on how they work but I think it will be trivial. In fact I’m so sure of it that if you try some Fillmore valves and aren’t impressed I will buy them from you.
Presta lover doing a quality bit of astroturfing ?
Bought them, pretty convinced already - made getting my gravel tyres on considerably easier. Got a set ready to go on the mtb wheels as well. It works, it's less hassle. Hopefully they'll get cheaper over time.

Surprised there isn’t a Rockbros rip-off version available yet?
Strange. Our bikes get ridden a LOT. I check the pressure before every ride. Same sealant in all bikes. E bike and my bike never clog, girlfriends always does. How do you explain that!?
I stopped reading when I got to the £39.99 bit.
Yep. Price is ridiculous. Even cheap valves are way more expensive than inner tubes, which is pretty daft, but these take it to another level. Probably could've saved all this hassle if we'd settled on schrader instead of presta
