Reserve Fillmore Tubeless Valve

I would have never thought I'd be willing to spend so much on something so basic, but I liked these so much on my gravel bike that I got another set for my MTB. It's not that it's knock-your-socks off advanced technology. I've never had clogged valves, which seem to be the Fillmore's main selling point. I like them just because they work so well you don't have to think about them anymore. I haven't successfully set up tubeless with these valves with just a floor pump, but my Airshot does the trick without having to remove any valve cores. And I can use a Lezyne pump without having to worry about accidentally unscrewing the valve cores. And I don't have to worry about bending or otherwise damaging those spindly Presta mechanisms. Maybe others don't have these issues with traditional valves, but it's happened to me enough that I'm happy to remove these headaches from my life and just enjoy the ride.

These valve stems make running tubeless tires a dream! The stems are easy to install. Once installed, these stems allow more than enough air to pass through them that mounting tubeless tires can normally be accomplished with just a floor pump. In addition, these valve stems do not clog! I have converted all of my wheels (all tubeless) to these valve stems.

Easy tires I ever seated. No sealant seepage during inflation. Rapid inflation. Truly incredible and well worth the cost of upgrade. I got 99 problems but valve cores are no longer one of them.

Got these with a coupon for my new gravel wheels, along with new tires. At the same time, was also mounting a second set (mud) tires on my other gravel wheelset, so I got to A/B the Fillmore vs. the standard Presta setup. Valve installation is as easy as Presta, but where Presta requires removal of the valve core for tubeless tire installation, potential clogging of the core and need to keep replacements handy, Fillmore does not. Same for adding sealant--just put it in through the Fillmore. No fuss, no muss. it really is that easy and clean.

The only thing I can see becoming a problem is losing one of the metal caps, but for now I am very happy with these valves.

I know people are pissed that these valves are so expensive, but holy schmokies I am a lifelong rider and an old woman and was able to set up my first ever tubeless tires with Fillmore Valves and a regular pump. I did not want to buy a compressor or special pump or go to the gas station to inflate bike tires. I used 24mm WTB tape (two wraps), Schwalbe 40mm G-One Allround Performance 700x40 gravel tires on WTB i19 TCS wheels, Fillmore Valves, and Muc Off sealant. I was so damn surprised that before I added the sealant that the tires inflated right away AND held air. I poured the sealant into the tire as opposed to using the valve because I felt like it was going to take too long for the Muc Off to work it's way thru the valve. Really - just a regular pump!

Great concept and well made just wrong size for my rims

These work great on my mountain bike but were not long enough for the rims on my gravel bike. Another issue is you have to use the cap. (The thing you have not used for years.) You better hope you do lose the cap. There is no easy replacement is available. That means buying a whole new set. Ouch!

I really love how much easier these are to get sealant in and out of than a traditional presta valve. Set up is pretty straight forward and they happen to look great as well.
