The supremely stylish all-alloy Mountain Pipe is a high quality hand pump with a CO2 inflator built right in – the total inflation solution! Using Twist-To-Inflate technology for fast, easy and controllable inflation, the CO2 cartridge stores in the handle when not in use but also doubles as a handle extension for manual inflation. Includes 1 x 16g threaded cartridge, a magnetic closure to keep the barrel locked firmly in place and a hidden container inside the handle containing a Schraeder adapter and 2 glueless patches.
