Hi flow, no clog valves for your tubeless tyres. The revolutionary Fillmore Valve lets you easily seat a new tyre and stops crusty-old sealant gumming up your valve core.
The concept seems quite good but they take a bit of getting used to. The valve cap can be a bit fiddly to attach and it is harder to add sealant when the valve core can’t be removed. There is definitely higher airflow than a traditional Presta valve although it still took a bit of effort to seat my tubeless road tyres. Just don’t lose the valve cap.
New ZealandFirst time I fitted these valves I thought I had wasted my money, the stems were too short so that the nut only just caught the first couple of turns on the threads. This meant that my pump just fitted, but my pressure gauge was too deep. ( bontrager rims on a 2021 Trek Fuel EX8 ) So I took them out and thought about it for a week, tried again the following week and realised the red wedge shaped seal was not going into my rim enough, so I replaced it with an O ring, allowing the stem to sit 5mm further into the rim. Been running them successfully ever since. I cut the top off of a plastic valve cap and stuck that onto the end of my tyre sealant syringe, as the tube that fitted inside a standard stem was too small to fit over these. So a bit of adaption needed to make them work, but I’m very happy with the result, I just hope I do not lose a cap as replacements do not seem to be available.
New ZealandThese valves are great. Easy installation and full flow makes pumping tyres up a lot easier
New ZealandFor the first time ever I managed to get a new tyre up on the bead with just a floor pump, using one of these valves. No compressor – impressive. Neat little devices and amazing to think that the Presta valve has gone so long unchanged...
AustraliaExcellent valves. Use something as a small funnel to get the sealant through the valve. Tyre was seated with just a track pump due to extra volume on valve. Don’t lose the cap!
