The custom cap has been specially designed and has an integrated core remover for removing and tightening the core without any additional tools. The nut has also been designed so that you can get a good grip on the flat edges to firmly tighten the valve on the rim.

An O-ring is included and sits against the outside of the rim to prevent damage to the rim.

How to install: Remove valve cap and nut, insert valve through rim, fit o-ring to valve then thread nut on and tighten by hand.
