e*thirteen Tubeless Valve Set

From the coil-sprung Dropper Post to the unique polygon crank interface, The Hive's e13 brand is focused on engineering original solutions for mountain bike components, as evidenced here.

The aluminum tubeless bodies are designed to maximize airflow and with the Presta cores removed the difference in air flow between these valves and anything else on the market is audible. Airing up a 29+ tire with my floor pump comparing the e13 valve, Stan's valve, Mavic valve and Schwalbe valve it's absolutely no contest; e*thirteen moves more air.

The valve set is more complicated than other options on the market (other than the less-than-recommended milKit) with multiple pieces. The inner body has a choice of a standard o-ring or a formed rubber spacer depending on where it is being used with a flat rim or a curved rim and the outer body also has a captured o-ring to protect my rims and ensure a perfect seal.
