The Birzman Diversity 17 is a compact, lightweight multi-tool designed to handle a wide range of roadside repairs. With 17 integrated functions, it equips riders with the essentials needed for tightening bolts, breaking chains, and fixing flats while out on the trail or road.
A standout feature is the integrated CO₂ valve head, equipped with Birzman’s patented Activate Valve Function, which releases CO₂ with a simple press on the head for accurate and controlled inflation. The valve head is compatible with both Presta and Schrader valves and works with 16 g threaded CO₂ cartridges, making quick tyre inflation simple and efficient.
Despite its functionality, the Diversity 17 remains compact and easy to carry, measuring just over 100 mm in length and weighing only 180 g—ideal for storing in a jersey pocket, saddle bag, or backpack.
“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
