🔥 Valves for Life

If you manage to break, snap, bend or crack our valves* then we'll fix or replace them free of charge!

⚔️ INSERT COMPATIBLE base

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!

🔧 Spoke key cap

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.

💨 Valve Core Remover cap

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:

Unscrew the valve cap
Slot the valve cap over the valve core
Twist anticlockwise until the core can be pulled out
Repeat in reverse to refit

Road rims: 60mm
Deep Section Road rims: 80mm

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

Ok so there's a few conditions. Valves are warranted for life to the original owner only and the warranty is limited to the replacement of tubeless valves only. valves will be replaced like-for-like (same colour / same length).

valves will not be warranted in the following situations:

If they have snapped or threaded from being over-tightened
If they have clogged with sealant
If they have been intentionally broken
If parts have been lost

Are tubeless valves universal?

Peaty’s MK2 Tubeless Valves are compatible with any rim with valve holes to suit 6mm presta valves.

Do tubeless valves work with tyre inserts?

Yes. The addition of a unique four-way x-cut base to enables our MK2 valves to 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 also 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!

What size tubeless valves do I need?

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.

Which of our valve lengths will fit your rim best will depend on your specific rim and 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.

If you’re still not sure then drop us an email and we’ll happily help you out!

Can I inject sealant through the valve stem?

We can’t speak for all types of sealant but our very own Holeshot Biofibre Tubeless Sealant can be injected directly through a de-cored valve without any issues. Simply push the 120ml trail pouch straight onto the valve stem or use the flexible injector pipe provided with our 500ml and 1L sealant packaging to inject the desired amount of sealant directly through the de-cored valve stem.

What happens if I snap a valve?

Get in touch with us through our valve warranty page and we will replace it with a new one free of charge providing you can display proof of purchase, photo of your damaged valve and a description of what happened. We’ve got your back!

Are the tubeless valves Presta or Schrader?

Peaty’s Tubeless valves are Presta valves. Presta valves are 6mm diameter whereas Schrader valves (the kind you usually see on cars) are 8mm.

How do I inflate the valves?

You can use a track pump, CO2 Tyre Inflator or air compressor to inflate your tyre through your valve.
