The Lezyne RAP – 15 CO2 Multi-Tool features 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, and an internal sleeve unthreads from the chuck revealing the engagement port for a threaded CO2 cartridge. The head threads onto either a Presta or Shrader valve and is made up of a lightweight and durable aluminum construction. Whilst being an efficient CO2 Dispenser the tool also comes supplied with Hex bits 2 – 8mm, Star shaped T25 and T30, Phillips Head, Chain Breaker (9/10/11 speed), Spoke Wrenches: Mavic Mtv, 3.22, 3.45. An all encompassing tool that can see you out of most road or trail side problems.
