Pump & controllable CO2 canister are a good combination IMO. The pump to get the air needed on the tyre to fit and then initially inflate further so not wasting part of a CO2 canister if their is a faulty valve, then the CO2 canister to quickly inflate fully. Pity no one seems to make a controllable CO2 valve with a pressure gauge on built. As for the requested recommendation I have a Lezyne road drive pump which is fine.
Perfect! I ended up ordering the pocket rocket though so hope it will also be a good choice.
