The Diversity 17 has, as its name suggests, 17 features packed into its small lightweight body. Apart from the CO2 valve head, it also offers the rider solutions for tightening bolts, breaking chains, and changing tubes.
The CO2 valve head features Birzman's patented 'Activate Valve Function', which releases CO2 with a simple press down on the head, allowing accurate controlled inflation. The head is compatible with both Presta and Schrader valves; 16 g threaded cartridges.
“Our biggest surprise was the integrated CO2 valve head. It works well, and the spring-loaded head does a decent job of controlling airflow too. At 180 g and just over 100 mm in length, this is a handy tool to stow in your pack.” - MBUK
