Sea Otter release.
I have them on my MTB (We Are One Union Rims).
I’ve never really had a problem seating Maxxis MTB tires with just a floor pump and didn’t notice a difference with the Filmore valves. It definitely takes less pumps to fill a tire. You can shoot sealant easier through the valve without it getting clogged. On a standard tubeless valve, I just remove the core to do this so its not that much of an advantage.
Two big cons I have noticed
- They do not work with a Topeak D2 SmartGauge*. They may not work with any standard presta gauge. Their unique design basically applies too much force and you can’t get inner valve(?) to depress and let air into the gauge. * if you put a presta/schrader adapter on the valve and then use the D2 Smartgauge in schrader mode it kinda works but that’s a pain.
2.If you lose the valve cover/cap they come with, you are screwed because they are unique and you need them to keep the valve from getting bumped/losing air/filled with crud.
Bringing up this old thread as I just installed two more Fillmore valves.
My Reserve 40|44 GR wheel set I got last year came with standard valves. Had never used the Fillmore so didn’t think too much into it. During a ride I went to unscrew a cap once and the core came out on the traditional valves and I lost all my air. I was able to hand tighten and pump up so not a huge deal. After that I packed a little core removal tool in my bag in case it happened again.
This winter I bought a second Reserve wheel set, the 42|49. This came with the Fillmore valves. Wow do they take some air fast, and overall just seem like way better quality and less moving parts.
I picked up a second set of the valves for my 40|44 wheels and installed them today. I quoted the above section today, because as I was playing musical chairs moving tires around to different wheels and such today, I noticed I didn’t need an air compressor on a single wheel with the Fillmore valves. This is likely due to the floor pump pushing in so much air faster that it holds its shape more between pumps and sets in place easier.
