Specifically designed to work with tubeless systems.

76 Projects' HI FLOW valves have 4x the air throughput and a redesigned core that helps prevent sealant build-up.

Tubeless bike tyres and rims were introduced 20 years ago yet tubeless systems still use the Presta valve standard. The clearances in a Presta valve are smaller than the holes that sealant is supposed to be able to block so it's no surprise that the valves get clogged.

  • 'No Clog' internals - Greatly increased clearances prevent sealant build up.
  • 4x greater air flow (compared to Presta) - Fill the tyre faster to help seat and seal the bead.
  • Sealant can be directly injected through the valve centre (see pic). Because the valves allow such fast and reliable inflation we recommend adding sealant directly to a unseated section of the tyre.
  • Compatible with rims having holes for Presta valves.
  • Just 9 grams a pair.
  • High precision CNC machined aluminium.
  • Completely rebuildable for cleaning.
  • Spare parts available here.
  • Size 1 Compatible with rim protection inserts



Size 1 - 15-35mm rim height* Compatible with rim inserts

Size 2 - 30-50mm rim height*

Size 3 - 45-65mm rim height*

*unlike normal valves our HI Flow valves are specified by the rim height rather than the valve length.

    BANG! The bead snapped into place almost instantly. We really did not expect such a dramatic result. We always use a small amount of soapy water to assist seating, but used very little this time and can only attribute this to the much higher flow rate of the valves.


     What can I say? These are the future of MTB valves. Why would you use a Presta valve ever again when these are available?

    One of the best products I have tested to date and I will be fitting these to all my bikes in the near future.

    ‘Hi Flow’ Tubeless Valves – the end of Presta?

    I fitted a pair and BAM! Well actually more a poof! I was able to seat a pair of Schwalbe X-One tyres to some Mavic Open Pro UST rims using just a track pump. It was easy, just a few strokes and up they went. So, so far the ‘Hi Flow’ valves have impressed. They stayed sealed, no leaking around the valve, I’m happy.

    If you're constantly unclocking clogged Presta valves or running a tubeless setup, the 76 Projects HI FLOW 'No Clog' Tubeless Valves are an absolute must-have. Although it takes a little more to install them, they perform exactly as promised, making tyre inflation much quicker and easier at a price that's incredibly competitive to traditional tubeless valves. These valves may just spell the death of Presta.

    valves of awesomeness

    i have tried different tubeless valves and they all clog or loose air, then i tried these and the no Clog from 76 works perfectly. Easy to install, easy to inflate the tire and just works

    Excellent valves

    Quick delivery, easy to install, great air flow, I managed to seat tyres with a small hand pump. Only issue I had is I lost valve cap on second ride.

    BEST VALVE EVER!!!!!!!

    I have been using presta valves for years but this thing is amazing no more clogging from sealants and its easy to unscrew the lock nut unlike presta valve lock nut that keep getting stuck.

    Valve review

    These are nice valves and I especially appreciate compatibility with inserts. It would be nice to have spacers for flatter and thin rim profiles out of the box. Also I find I had to change my technique to close valves, pulling on the valve, else I’d inadvertently let out a good amp of air

    Easy installation and reliable

    I read about these online when I was looking for a way to solve my tubeless clogging problem. The one thing that struck me was the unconventional way to install it. It's only unconventional because it doesn't follow the insert-then-secure method like contemporary valves, which this obviously wasn't. After **** the whole thing on (took only about a minute); it's done! I'm into my third week of use and there's absolutely no sign of a clog. Secondly, this is the only valve I have where I absolutely have no need for a pressure canister to seat the tires on my road and gravel bikes.

    The only gripe I have is the necessity in using a chuck adapter with my Lezyne pumps. While they fit great and work well, I wish the valves were designed not to need these.
