This aluminium mini pump punches well above its weight. It Inflates to 40psi with no drama and is fully serviceable. It comes mounted to a bracket that fits to bottle mounts, or under a cage, and this bracket also holds two C02 cartridges (supplied), which are activated using the braided steel pump connector hose.
This is great for getting going quickly, especially if you’re in a race or in bad weather. The hose itself is fantastic – a heavy-duty braided unit with a reversible chuck to suit Presta and Schrader valves on one end, and at the other end it’ll either screw into the pump or directly on to one of the C02 cartridges. It’s a buy-once item – just replace the C02 when needed.
