HI FLOW 'No Clog' Tubeless Valves

Specifically designed to work with tubeless systems.

NEW SUPER SHORT SIZE 0 & EXTRA LONG SIZE 4

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, adaptor required for screw-on inflators.

ADDITIONAL INFORMATION

• *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.
• WORKS WITH LEVER LOCK STYLE PUMPS AS STANDARD. ADAPTER AVAILABLE FOR USE WITH SCREW-ON OR DIRECT PUSH-ON** PUMPS. Select as an option or available here **No adaptor required for One Up EDC pump

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.

	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.

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. Paul Horta Hopkins

	https://off.road.cc/content/review/components/76-projects-hi-flow-no-clog-tubeless-valves-9075 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.
