TCS Max-Flow Tubeless valves feature a foam insert-compatible base, increased bore diameter, integrated valve core remover and an ergonomically designed nut that allows riders to properly tighten the valve without using a tool. TCS Max-Flow Tubeless valves feature a crenellated base for multidirectional airflow on the sides, thus preventing the airflow restriction that can occur when a tyre insert is pushed against a traditional valve opening. The increased bore diameter helps to seat Tubeless tyres and also helps prevent clogging that would typically occur after pouring sealant through the valve.
