Details

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 from the 1890's. 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). However, because the valves allow such fast and reliable inflation we recommend adding sealant directly to a unseated section of the tyre.
  • Just 9 grams a pair.
  • High precision CNC machined aluminium.
  • Spare parts available here.
  • Sizes 0 & 1 Compatible with rim protection inserts.
  • Compatible with push-on CO2 inflators, adapter required for screw-on inflators.

      Use the message facility -> if you have question that isn't answered here.

      Can I inject sealant directly in to the valve? The valve 'core' is hollow so sealant can be injected directly via a 5mm internal diameter tube. Simply undo the brass nut, and make sure the valve 'core' is pushed down.
      However, we always recommend unseating a section of tyre and putting sealant directly in. That way the sealant level can be observed. Because of the hi-flow nature this method is much easier than with presta valves.
      *Some sealants with very large particles such as Silca Ultimate may still clog in some circumstances. For these sealants we recommend added directly to the tyre rather than through the valve

      Are valves compatible with tyre inserts? Yes, size 0 and 1 valves have base nuts with side ports that are compatible with tyre inserts.

      Are the valves compatible with Tyrewiz? No, tyrewiz requires and presta style valve.

      Some sealants with very large particles such as Silca Ultimate may still clog in some circumstances. For these sealants we recommend added directly to the tyre rather than through the valve and also not to remove air via the valve when the valve is at the 6 o'clock position.

      Due to the hi-flow, if the tyre are deflated with the valves at 6 o'clock the sealant may be siphoned out of the tyre. For that reason the valve should be at another position.

      Valve Rebuild

      ‘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. Cytech Review

      Bike Rumour


      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.

      HI FLOW VALVE OVERVIEW

      Despite fitting in the same size valve hole and using the same pumps as presta Hi Flow valves have a unique precision CNC'd construction which enables 4x the airflow.

      HI FLOW 'NO CLOG'

      Hi Flow Valves valves feature a unique hollow precision CNC'd stainless steel valve core. In combination with the wider 'transfer chamber' section it means that 4x the air flow is achieved versus a presta valve.

      The greatly increased clearances also mean that clogging is far less likely. Whereas 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 they get clogged.

      VALVE SIZES

      Size 0 - 09-20mm rim height* Compatible with rim inserts - MTB

      Size 1 - 15-35mm rim height* Compatible with rim inserts - MTB / GRAVEL / ROAD

      Size 2 - 30-50mm rim height* - GRAVEL / AERO ROAD

      Size 3 - 45-65mm rim height* - DEEP SECTION AERO

      Size 4 - 60-85mm rim height* - DEEP SECTION AERO

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

      ADDING SEALANT

      Sealant may be added directly through the hollow valve core via a tube with an internal diameter of 5mm. However, we always recommend unseating a section of tyre and putting sealant directly in. That way the sealant level can be observed. Because of the hi-flow nature the direct method is much easier than with presta valves.
      See video for tips on adding sealant.

      *Some sealants with very large particles such as Silca Ultimate may still clog in some circumstances. For these sealants we recommend added directly to the tyre rather than through the valve.

      PUMP COMPATIBILITY

      Our Hi Flow valves work with pumps lever lock style heads.
      Screw-on style heads such as found on Lezyne hand pumps, or push-on* such as the Lezyne speed chuck will require an adapter.

      Adapters are available to fit Presta or Schrader style pump heads. Schrader is the version supplied if you select the option to buy with valves on this page.

      *No adapter required for One Up EDC pump. Topeak Smart Heads also require an adapter. .

      Well.. 2nd time...

      These valves for my BI forty five, I bought because I had good experience with the valves on my MTB. - Nice valves and a fast delivery.. This time the valves feel no different from the standard valves i used before.. - maybe clogged? AND not to mention that the €17 in postage that would usually be for an over night delivery, is ABSOLUTELY INSANE when delivery is almost 2 WEEKS! - 76Projects can do MUCH better!

      Hi Jeppe, it's unlikely they are clogged. We will email you with a list of checks.
      Regarding the delivery, you ordered via our UK site, €15 is not unreasonable for international shipping. We have a EU site which is what you used previously and that would be faster and more cost effective. Customers should get a pop notification about our Eu oand US sites but this may be blocked be pop up blockers.

      Hi Flow Valves

      Easy to install and make tubeless set up a breeze, even the most stubborn tyres seat on the bead with minimum effort

      Best valves that I have tested, no deflated wheels. Easy to install and has made tubless easy for the first time. Also the price is really good compared to the Fillmore valves

      Massively Disappointed

      Can’t get either standard pump on or charge pump.
      Also they insert outside wheel with locking inside tyre. Can see it causing problems
