With design, sustainability & quality running right to the core, there’s only one company Peaty's could work with on their valve colors - Chris King! With a valves for life guarantee and Chris King's stunning colorways, your bike is in for a real treat for years to come! The MK2 Valves have an x-cut base, designed to work with all tire 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 airflow when tyre inserts are not used. Valves come as standard with an integrated valve core remover cap and spoke key cap (for standard 3.4mm spoke nipples). This makes tightening loose spokes and topping up with sealant a breeze, either in the workshop or out on the trails.
