Fillmore Valves

Expensive

Familiarity:

I've used it once or twice and have initial impressions

I bought these on the claim of ease of tubeless set up. I could not get sealant to flow through the valve as they claimed. Since there is no valve core to remove you have to insert sealant through the edge of an unseated tire. Tubeless set up messy and harder. Can’t think of a reason to purchase these especially at a significant premium to other great valves.

90mm

Easy to put sealant in and release air. so far so good no leaking air.

Awesome!!

A lot of people buy these to avoid clogging, that’s not something I previously experienced. I like these so much for the ease of adjust air pressure. So sweet!

Love them

I installed these on my primary wheels for my gravel bike a year ago. Two months later I installed them on my 650b wheels after loving how they work. And now the commuter gets these valves. The design is much better than a presta with much more air going into the tire and much less clogging at the valve. Contrary to comments below, you can add sealant through the valves and it looks, from the reserve wheels website, that they have added a 70mm and 90mm valves to the existing 50cm valves for those with deeper wheels.

Not good for adding sealant

These are obviously solid stems (but be careful) - they are so stout that if you side them on a rock you could easily damage the rim hole. However, I am returning them for another obvious reason that I should have seen before buying. You cannot add sealant by removing the center and hooking up your Stans Bottle device. VERY inconvenient. Buyer beware

Way, way too short

These are listed at 50MM, but that's all in. In reality, by the time you add in the red cone the short thread stack, they are closer to 25-30mm. For reference sake, I'm using Winspace Lun gravel wheels, which are listed at 38mm deep. The valves are so short I couldn't even thread the lock nut. Bummer, but I think these would be way easier to use than traditional valves.

No more hassle

If you want to seat new tubeless tires easily, this is the way. I can imagine price around $30 range, but I do still think it was a good investment. I wish they would make road bike compatible too for the deep dishes.

Not long enough for TRS 249 Reynold rims

I returned this product before using it

Wanted to give someone heads up if they're buying these for their TRS 249 Reynolds rims. The 50mm stem was NOT long enough, so don't buy these stems until they offer longer stems. I purchased these stems b/c I've had (2) friends tires go so flat at the trail head that the old presta stems wouldn't take air via Ryobi air-pump and had to drive to a gas station / bike shop. Of course we could have use C02 but then we'd have to change out our sealant later. So if these new Reserve Stems save me one time, it's worth it! But yeah, wish they were only $ 38 for the pair.

Really easy to setup

It's true you can set up a tubeless tire very easily with just a floor pump when you have these installed. At least the two I did, no issues at all. The design makes a lot of sense when you actually have them in your hands. Makes you think you should have came up with this idea, it's just a much better way to get air in a tire and keep it there. Dropping a psi or two mid ride or where ever is slightly easier than a traditional valve too, no core to unthread

Too short for lots of rims, but awesome!

Not much more to say. Actually, a trailside pump broke some threads off of one...so you couldn't put the cap back on. Turns out you don't actually need it. But anyway, Reserve sent a free extra replacement set. Just wish they were longer so I could run them on more of my wheels.
