With design, sustainability & quality running right to the core, there’s only one company we could work with on valve colours - chris king!

MK2

• Still made Made from lightweight anodised 7075 aluminium as standard, 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.

Insert compatible base

• The addition of a unique four-way x-cut base to enables 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, 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!

What Size?

MK2 valves come in 42 mm, 60 mm and 80 mm 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: 42 mm
• Road rims: 60 mm
• Deep Section Road rims: 80 mm
• Always measure your rims before purchasing or contact your Rim manufacturer for further recommendations.

Fitting instructions

• Remove valve cap, o-ring and lock nut.
• Insert valve through valve hole in rim.
• Push the o-ring onto valve stem.
• Thread the lock nut onto valve stem.
• Hand tighten lock nut until firm.
• Screw on valve cap.
