This is an example of something been an overcomplicated solution. It works, I might even buy them. But a Schrader valve is still a cheaper solution that works just aswell. There's also no particular reason you couldn't make an 80mm Schrader valve for deep wheels either. It's just a poorer standard presta won over

[@svetiksvetik6521]

Tell me, please, which spokes (multicolored) are shown in this video?

[@OriginalGabriel]

At that price point, they really need to include replacement o-rings, and caps.

[@WIPEYOURLENZ]

Or include the rest of the bike 😂🤣😂🤣

[@Jocool0785]

They come with a lifetime warranty and can contact them about lost caps. What more do you want?

[@26realmc]

@RollinRat any other high flow valves out there at a cheaper price point?

[@idlerfang]

Also you will need to remove the tires to access the o-ring. On Presta valves you just remove the old core and replace it with a new one, which costs much less than $1 and can be done in literally seconds.

[@elitebicycleracers]

You can purchase a bag of o-rings like this for pennies per o-ring.

[@MTB_Rider_96]

It's about time someone redesigned the Presta valve! But yes, $50 is a lot to pay for a valve. I will be buying for all my bikes though.

[@The2808erik]

They are almost twice the price of premium presta tubeless valves, but the longevity seems to be there. I'm curious how long it takes to get the o ring to fail.

Presta valves cost $10 for a pair. They have replaceable cores and are essentially indestructible as long as you don't ham fist them. And if you do, just change out the core. These reserve valves seem cool but i wouldn't pay an extra $35 for them.

[@DosJof5118]

It costs a lot to manufacture itty bitty parts like that, but worth every penny or in this case dollar. I am using the Fillmore valve on all of my tubeless setups and simply love them. Remember if you introduce your children to the sport of cycling they will never have enough money for drugs.

[@cup_and_cone]

Now that rims are getting wider, it would be nice if the industry switched to schrader valves...

[@LandonArkens]

I drill out my rims and use Schrader tubeless valve stems. A pair on Amazon costs $10.

[@The_Ultravisitor]

if you don't dare drill your rim, you can remove the valve core and put a presta to schrader adaptor on. cheap as chips.

[@LandonArkens]

@@The_Ultravisitor I didn’t realize there are actual converters, not adapters. very cool. Thanks for the tip!

[@cup_and_cone]

@RollinRat I remember split tubes... I used to use 20" BMX tubes on 26" rims, then trim the overhang after inflated. Easiest hack to get reliable tubeless back in the day with Stan's.

[@GerardCantor]

I've always found the Presta to be problematic. As you say, the tip bends easy and it's not great in tubeless set-up (i.e. they get clogged easy). If the Fillmore changes all that, and offers more airflow in and out, then I think it's a game changer. New tech is always pricy. Hopefully with time, and more units made the price goes down. GREAT review, thank you.

[@kalso69]

@rollinrat4850 this is OK if you're addressing the airflow ONLY. but this suggestion is irrelevant to the advantage of going tubeless.

[@kalso69]

@rollinrat4850 your initial suggestion was “go get tubes” so I thought it was not a tubeless setup. Now your last reply makes more sense. This will work for sure. 👍

Wait a minute, I fill the sealant through the actual valve mechanism right around the seals? Sounds even more clog-prone than the standard procedure of removing the presta core and filling it in..

[@BIKEPACKINGcom]

Yep, directly in the valve or you could always just pour into your tire. it's not more prone to clogging because there is much more space than the Presta valve core, MUCH MORE!

[@Jocool0785]

Also airing up you tires after adding sealant would clear out any extra sealant.

[@joshuadoss1955]

I really enjoyed the video. The quick history of presta was cool

[@garethrobinson2275]

A lot of bitching about the price but this is a function of the development costs and relatively low volume manufacturing. I agree that there are cheaper options, especially converting to Schrader valves but it's nice to have one size fits all pump setup out on the trail. The problems with Presta are more of a trail issue than a shop one. In the shop you have high pressure and removing a fiddly valve core is no issue. On the trails I've experienced the kind of problems outlined in the video. To me this seems like a superior design and wider adoption would bring economies of scale which is where the price problem falls away. I love great engineering so I might give them a go on one of my bikes and go from there.

[@jonpoon3896]

The price might be worth it. You say 4 presta valves for 2 Fillmore valves. Well, if you bend, clog, or mess them up in other ways, you’re gonna end up buying more anyways. “Buy cheap, buy twice”

[@TrekSLDuraAce]

Lately the trend for wider tires has also led to wider rims. Therefore, we no longer have the need for small diameter Presta valve. I'd like to see Reserve (or a competitor) make a similar design but with the diameter of a Schrader valve. Wide tires on wide wheels needs a bigger valve, yes? Reserve should take a lesson from Henry Ford. He lowered the price of his cars, and sales went through the roof! You can make more money by lowing the price and increasing the volume of sales. Just a thought.

[@p8ddy]

It strikes me a solution to something that really isn't that big of a problem - and there's already a better and much cheaper solution - the Schraeder valve. Fillmore valves - helping push top end bikes further into mortgage level pricing. It's dumb that a pedal bike costs more than motocrosser, and the incredible number of non standard 'solutions' simply locks out smaller manufacturers like Hope and locks in less value and more profit for the big guys. In the early 2000's I was able to run the same full sus bike with similar spec as DH world champion contenders, and the price wasn't astronomical... Now, a similar spec bike costs more than a 'crosser and more than some new cars - and the tech hasn't improved that much, unless you count creaking bottom brackets, carbon frames that can be written off by a stone chip and weaker wheels as improvements...

[@johnstarky]

[@Alex-ig7li]

When you need to fill more air into the tire? You have to remove the cap - but the air stays inside the tire ? Because of the pressure in the tire?

[@fotografamos4083]

I'd say so. The pressure in the tire will push the core of the valve outwards, thus closing it.

[@BIKEPACKINGcom]

Correct, so essentially you could ride without the cap.

They're probably comparing with the valve core on. But you would remove the core to bed your tyre in, at least for your first setup, hence pointless comparison. Presta without the core will have exactly the same airflow as fillmore. Marketing guys trying to fool ignorants again and try to justify their 50$ price

[@nemeanf27]

Shame that these are only for up to 28mm depth rims. I'd get these if there were a longer road version.

[@chrisdinsmore1665]

According to their website they make three sizes. The largest is 90mm and fits rims 48mm to 68mm deep.

[@OniMetsuki]

Nice, but not at that price. Taking out the traditional core is not such a hassle + this cannot be done on this new valve if you need to without removing your tyre....

[@ericpmoss]

Given that super narrow rims were a goofy idea even for road bikes, should Presta just go away?

[@Jocool0785]

It's surprising but with the internal core spring, Shrader valves (even with 8mm diameter) actually have less flow than the Presta. By reconfiguring the valve internals, the Fillmore is able to achieve 3X the flow of the Presta

[@jonathansanchez1305]

Presta can hold more air since the valve is kept closed by the nut on the valve.. if we put those on our air shocks we would see less air loss which happens on the return stroke for the main chamber or on the compression stroke for the negative chamber if the piston moves faster than what the valve spring can hold back. The real question is why aren't presta valves used on shocks (or perhaps why schraders aren't used on mountain bikes if what you said about them were true)... And I'm sure the answer would be because schrader valves have been around for a century or more and more readily available and mass produced...

[@jrbechthold]

I don't always try to replace a design, but when I do I make sure to make it ultra-complicated with unique, impossible-to-find parts. $10 says these were designed by a former BMW engineer. From the tiny pin, to the unique stem with a very strippable allen head, to the end piece that's going to eventually seize on there and make service impossible, what a joy. Oh, and don't forget that you get the pleasure of pulling off your tire if you need to work on it. Presta isn't great, but having an easy-to-replace core is the way to go. KISS, designers.

[@manargias]

Mucc-off sealant clogs them. Used Stan's injector to put Stan's sealant repeatedly for months and worked flawlessly every time. Then I switched to Mucc-off sealant with different tires and after injecting it through the valve with Stan's injector the valves immediately clogged! Don't inject Mucc-off sealant through them, you'll throw away 50$.

[@dp5383]

I will say presta holds air better/longer than schrader.

[@keacoq]

There is a saying in France expressing frustration with bureaurcacy: " Why do simple when you can do complicated? Presta valves correspond to complicated when you can so simple schrader. The simple solution is surely to use schrader valves in every situation except for very narrow rims. My problem is that I have found it difficult to seal around a schrader valve for tubeless. The rim surface inside the rim is often curved. A flat surface would make it easier to ensure a good seal around a schrader valve. Problem then fixed with cheap existig tech.

[@N6J6R6]

So you still use the Presta air chuck to pump up your tires with these? Also, how do I know what MM length to get?

[@Whyusadd]

These are great, pumping up tyres is easier. Tubless syringe doesn’t require the valve core to be removed… great product… and yes worth the money!

[@jimihenrik11]

So these wheels cost 50$? That's quite reasonable. What, you mean the valve alone is 50$, gtfo! I think prestas are like 5$, so this is truly a useless invention.

[@a8f235]

If you care about tire pressure, why would you change it without checking it after with a tire gauge? Personally I am looking for new valves after my useless Milkit bs valves clogged after one single day, and I poured the sealant directly into the tire as well as having the valve pointing up the first night to prevent sealant laying directly on it. That's why I need something else, but I still try to figure out how anyone check tire pressures with the Fillmore valves?

[@meibing4912]

Too expensive - especially because they need maintenance - sort of negating any time saved. Also adds complexity, who needs that?

[@Prosecute-fauci]

I’m just sitting here wondering how you are supposed to check sealant level with this valve installed

[@locoshaggy]

There is nothing better than presta! clogging of the valve can be removed by putting a little solid vaseline inside the ovule of the valve that opens and closes. This prevents the sealant from sticking. Even to clean it, you can file the riveted top of the mini presta nut and disassemble it into 3 parts, clean it with thinner and apply Vaseline and you will never have a problem of it clogging again. The presta valve has no competition doing this, it has good flow, it does not clog and the tip is removable to add sealant.

I carry an extra and an cut spoke if I need to unclog my valve.

[@stefis6]

One problem with tubeless valves may be that they are secured on the rim only by friction fit inside the rim, and knurled nut on the outside of the rim. Even when finger tight, after time with sealant, the knurled nut might be too tight on the valve to remove the whole valve (not talking about the core) - which results in the valve simply rotating in the rim hole, rather than the nut loosening on the valve stem, when turned anticlockwise. You might have to do this out in the field to fit an inner tube. With Presta valves, at least they have a flattened section on the core, which allows use of a core removal tool to stabilise the valve when rotating the knurled nut. These new valves, while looking good, don't have that facility.

[@atelierrouelibre6522]

But you don't need to turn the knurled nut with a Fillmore valve. There are not any. To inflate, simply open the cap completely and plug in your pump. To play with the pressure, just open the cap a little and push it in. To deflate completely, open the cap and push down on the rod. No knurled nut. This is what looks great with these valves. I want to try ;-)

[@stefis6]

@@atelierrouelibre6522 there is a nut - it is the one on the inner aspect of the rim, holding the valve tube snugly on the rim. I see it in the picture!

[@atelierrouelibre6522]

Yes, but with the fillmore, i don't see why the valve will rotate in the rim hole... You don't need to loosen something, if I understand well. Just the cap, and you don't need force for that. For me the problem with presta on tubeless, it's that when I want to play with the pressure, it so hard to open the little nut glued by sealant. If I insist, the core turn before I can open the nut valve. I need to take a core tool to hold the core while I loosen the nut of the stem. It's really boring. (Sorry for my strange english, I'm french)

Will these fit any wheels?

I am less concerned over the price, more of the reliability. This is to improve not only seating the tubeless tyre, but also - in general - work better that 'easily bendable' presta valve-cores. Better core, better material used - I would accept that - IF that would actually work and be reliable. If there is already an issue or at the very least concern, regarding o-ring - then this is not what I am looking for.
