Santa Cruz BicyclesReserve Fillmore Tubeless Valve(Return to Product Page)

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.

Outstanding product! Better design, super quality. Makes tire mounting a breeze, but also sealant refill and pressure adjustment. Yes, don't loose the caps as they are larger than traditional presta, but you can forget the valve core replacement and tools. Just a superior product. Wait for a sale on BTD and buy.

Pricey for sure, but I've never had these valves clog with either Orange Seal or Silca sealant. I've have trouble in the past with Silca sealant in particular clogging standard presta valves.

Tubeless setup with a floor pump was very easy

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!

Constantly had to replace Presta valve cores in tubeless setup. These valves have proven to eliminate clogging. Best purchase ever in tubeless setup.

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.

Great concept and well made just wrong size for my rims

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.

These are great. They are silly-expensive for what you get, but they do exactly what they say, and they do it really well. And they look nice to boot. If you're looking for a splurge to get over a free shipping minimum, maybe not a bad splurge.
