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
WORKS WITH LEVER LOCK STYLE PUMPS AS STANDARD. WILL WORK WITH SCREW ON OR DIRECT PUSH ON PUMPS USING ADAPTER AVAILABLE here
Size 1 - 15-35mm rim height* Compatible with rim inserts
Size 2 - 30-50mm rim height*

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?
