The Lezyne Rap CO2 tool is a simple, ingenious tool with an integrated CO2 dispenser. The RAP CO2 line of multi tools feature a simple, yet ingenious, design that integrates a CO2 dispenser. The CO2 head quickly slides on or off the 5 mm bit allowing for easy access, & an internal sleeve unthreads from the chuck revealing the engagement port for a threaded CO2 cartridge. The head threads onto either a Presta or Schraeder valve & is made up of a lightweight & durable aluminium construction. Available in a 15- or 21-tool build, the RAP CO2 features our exclusive CRV+ corrosion resistant bits & ergonomic aluminium side plates.
