Birzman Sheath Apogee pump review

On the face of it, it's a pretty standard minipump. But the Birzman Sheath Apogee has a couple of useful tricks up its sleeve

Cycling Weekly Verdict

Combines an efficient minipump with the ease of CO2 inflation, for a failsafe inflation option. But the pump is quite short and there’s no regulation of CO2 output.

CO2 inflators get you going again far more quickly than a pump if you get a flat when out riding. They’ll also get a tyre up to around 100psi, which is hard work with most pumps – if I check tyre pressure when I get home after a flat mid-ride I usually find I’ve given up at about 60psi.
