Details

Specifically designed to work with tubeless systems.

NEW SMALLER SCREW-ON ADAPTER DUE EARLY DECEMBER

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.

Weight: 9 grams - size 2

Material: Precision CNC'd Aluminium

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. Off.road.cc

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.

*No adapter required for One Up EDC pump

Does not work well with pumps that use the TOPEAK SMART HEAD as the internals are not conventional. We recommend using the screw-on adapter for these pumps.

Work Perfectly

No more clogging, tyres inflate so much better.

Hi Flow valves

These things are awesome, made inflating tyres so much easier, you can install the fluid through the valve but it's messy, just install the fluid into the tyre and then seat the tyres as per the instructions. Connecting a pump to inflate isn't the best of fits, but the valves do work and look great.

Skeptical at first, now amazed

When I first received these valves after inspection I didn't use them, they just seemed so different and stuck to my go to valves.

Recently built up a new bike and finally installed these valves. They work amazingly well. The flow is soooo much better. Be careful airing down as it doesn't take much compared to old school vales.

Airing up so much faster as well, just few pumps and your there as your not fighting the clogged valve.

Best of all no clogs!

Work fine with One Up pump and generic floor pumps, I did not need any adapter.

When airing down be sure to redirect air away from your rotor as its easy to blast sealant out on first press it flows so hard and fast. Good stuff!

If your not sure, do it. Great upgrade. Nice work 76P, impressed.

Perfect flow

Project 76 is perfect for tubeless riding.
Due to the structure of the valve, you do not get latex clogging in the valve.
The tires can be easily inflated. Furthermore, they look slick.
