Introducing our latest innovation in tubeless valve technology: The Big Bore Valve range. Engineered with precision and designed to deliver maximum inflation simply and efficiently, this patent-pending valve sets a new standard and is the benchmark in high air flow tubeless tyre systems with a revolutionary ‘Straight through’ internal design, which means no clogs and maximum airflow fire power.
Featuring a cutting-edge, integrated ball valve system, the valve ensures lightning-fast airflow, turbocharging the sealant filling process. Say goodbye to the hassle of traditional tubeless valves that clog up and require the valve core to be removed to fill sealant and achieve sufficient air flow during tubeless set up.
Our Big Bore Lite offers up to 230% higher air flow than traditional Presta valves thanks to the straight through bore design.
With our ball valve construction and integrated lever, you can quickly open and close the valve for effortless airflow control, and even fine tune your pressure whilst you're out riding.

CHOOSE YOUR COLOUR
Choice of 6 eye-popping anodised colours (Black, Iridescent, Red, Blue, Orange or Pink).
60/70/80mm available in choice of 4 colours (Black, Iridescent, Red or Pink).
CHOOSE YOUR SIZE
When using with the Stealth Tubeless Tag Holder, please allow up to an extra 5mm of length when selecting valves on the website/valve length calculator.
Available in 6 sizes of valve stems to suit different rim depths. The length of valve you need will depend on the height/depth of your rim. You will need to ensure that you have enough threaded stem valve poking through the valve hole to not only secure it with the O-Ring and Lock ring but you will also need to be able to screw on the top half of the valve.

What’s the difference between Lite & Hybrid?
The lite version is slightly more lightweight and has a Presta fitment so will use a Presta Pump to inflate. The Hybrid version has an extra wide high airflow head which uses a Presta drilled rim but with a Schrader valve for a slightly higher airflow rate. Hybrid requires a Schrader pump which most pumps have.
Why switch to Big Bore vs current Tubeless Valves?
With a coreless ball valve it has a ‘straight through’ internal design it has maximum airflow. The means that you can inflate your tyres and add in sealant much quicker vs a regular Presta valves.
It delivers a higher flow rate of up to 264% vs standard Presta, meaning you can inflate in seconds versus potentially minutes, and even quicker with a co2 inflator.
In addition, with it having no valve core and a servicing kit coming soon, it means your valves will last for much longer and won’t need to be replaced as often.
