When Reserve Wheels launched their new Fillmore valves last week, you lot got quite worked up. Were they solving a problem that doesn't exist? What's ...

If it works… why buy the reserves then?
Could I buy the adapter on its own? It’s only happened once but Leyzene pump unscrewing the valve core… total PITA.
Am i the only person that has always put sealant in through their valves?
No I do as well with the core removed.
About time MTBs moved to Schrader valves. Presta is a relic of skinny road rims.
Goddammit, if I don’t get credited for my comment how can I try to claim commission from 76Projects?!?

Is the correct answer.

I was expecting to see this image to launch the thread.

Nah, I've had far fewer issues with Presta valves than Schrader, happy to keep using presta as it works very well.
However, each to their own, choice is good but presta works very well for me.
Whereas the Fillmore valves claimed 3 times as much airflow, the Hi Flow No Clogs claim 4x as much.
Note that both these and the Reserve valves are aluminium stems (whereas most *standard* tubeless valves are steel?). I rode with someone who'd paid a load for Peatys tubeless valves that both snapped. Theres not a lot of material on a valve stem they get yanked about quite a lot by pumps being put on and off.
Clogged valves drive me nuts; causes trouble doing the simplest task of pumping up a tyre and going for a ride. Waz that about and how can a bike be sidelined by the smallest most ridiculous component on it?
Is This The Original Hi Flow No Clog Valve?
Nope and neither are Reserve, Peatys or Muc-Off
miKit were, launched in 2015, still the most innovative design IMHO.
Bring back the Dunlop valve I say.

I used Schraeder tubes for years, then one day I bought some new wheels which were presta only, and I noticed that I was the only one of my riding buddies still using Schraeder valves. I don't remember there being any discussion, it just... happened.

You're half right there. They are no clog, but still have a core you have to remove if you really want to fire air in

Milkit are neither high flow nor no clog
Had an issue once back in the day when a Schrader valve had filled with mud rendering it inoperable.
I bought schraeder tubeless valves last year, still to fit them as drilling out my rims just keeps dropping off the to do list.
One day.

Somebody will hopefully come up with some kind of valve lid®️ to help stop that from happening

You should alert the automotive industry, before someone else suffers the same grisly fate.
I like the thingy at the bottom to keep inserts out of the way!
hi flow is any without the valve, just need to be fast with your thumb.
Shame about the pump compatibility- obviously you can work around that but there's times when you end up borrowing a pump. Have to admit I don't understand it, they have a thread, so what is it that stops a thread-on pump from working?
Agreed, was considering getting them but a pump situation that requires a small adapter always ends in trouble sooner or later
Is this a problem which really exists, I remove the presta core, pour in sealant, replace core then use a compressor to inflate the tyre which will completely clean out the valve.
The fact that your routine involves use of a compressor implies that it may well be an issue
so what is it that stops a thread-on pump from working?
Because the design uses a hollow core the brass nut at the end is much larger in diameter than a presta one. The larger nut does not fit far enough inside most screw on heads heads hance the need for the adapter. Because push-on heads compress on to the valves there is enough clearance.

Ashima had basically these on sale at Taipei bike show 4 years ago. I almost bought a load to sell under SuperstarComponents. Everything has been done before, don’t believe the hype.

I'm sure lots of products exist or have been shown at shows but if you can't actually buy them it's not very relevant is it?

Must be the PR department, can you put me through to the warranty department?
These are really looking for a problem that doesn't really exist!
Assuming setting up new tyres is not an issue from a blockage stand point, when changing tyres...
1) Remove old tyre and sealant
2) Clean up rim
3) Remove valve core and clean off any dried sealant
4) Visually inspect valve stem, maybe poke an old spoke through if it looks a bit gummed up.
5) Mount new tyre
6) Inflate dry to seat
7) Deflate
8) Add sealant and refit valve core
9) Reinflate
10) Have a beer...
When adding the sealant (and inflating, make sure valve isn't sitting at the very bottom of the wheel, otherwise the sealant just pools and will help block. Make sure wheel is positioned so the valve is sitting at about 4 or 8 o'clock then the sealant goes in and away from sitting at the valve.
