Still made from lightweight anodised 7075 aluminium as standard, our new MK2 tubeless valves are now compatible with all rim inserts and come with a spoke key cap as well as a valve core removal cap.

That's right ... the best just got even better!

The addition of a unique four-way x-cut base to enables our valves to now work with all tyre inserts.

The channels cut into the base of the valve allow air and sealant to pass through when inserts are pushed up against them.

Unlike most other insert-compatible valves, our valves have a ‘straight-through’ design so there’s no reduction of sealant or air flow when tyre inserts are not used.

All of this with no added weight!

Our MK2 valves now come with a world-first spoke key presta valve cap!

The spoke key is sized for standard 3.4mm spoke nipples and is the perfect tool for tightening loose spokes in trailside emergencies.

To use, simply unscrew the cap, slot your spoke through the gap in the top of the cap and slide down the spoke until the cap fits over your spoke nipple.

Whether you're in the workshop or out on the trail, our valve core remover caps help to quickly remove the valve core to deflate the tyre or top up with sealant.

To de-core the valve, all you need to do is:

1. Unscrew the valve cap
2. Slot the valve cap over the valve core
3. Twist anticlockwise until the core can be pulled out

Repeat in reverse to refit

WHAT SIZE DO I NEED?

Our MK2 valves come in 42mm, 60mm and 80mm lengths. This means that whatever the depth of your rim, we have valves to fit your needs.

As a rough guide, we recommend:

• MTB, Urban and XC rims: 42mm
• Road rims: 60mm
• Deep Section Road rims: 80mm

We recommend there to be around 15mm of valve stem sticking out from your rim - ultimately depending on the insertion depth required by your pump head.

The exact fitment would vary on how much of a dip there is in the rim bed. Some rims also have a recessed valve hole on the inside of the rim to reduce the length of the valve required.

You can check these lengths by:

• Poking a long thin object (like a spare spoke) through your valve hole then measuring the distance from the lowest point where the valve will sit into the rim to where the valve exits the rim.
• Measure the insertion depth your pump head by pushing your existing valve into the pump then marking where the valve stem exits the base of the pump head when pushed fully inside.

Add the first measurement to the second measurement and if this is less than 60mm then you should be fine.

Always measure your rims before purchasing or contact your rim manufacturer for further recommendations.
