• Lezyne Alloy Drive HV. Again works fine for MTB tyres and fits in pocket. Pocket Drive HV is good too for a really small pump that does large tyres

  • second for this (though mine is not alloy, it is HV drive). mine was attached to the bike (stored in metal shed) and in 2 years still fine no corrosion. I give the core a little tighten most times i use it and haven't had any issues myself. Does big volume good

    if you use canisters for anything other than emergency re-seat you're a bit of a dick, those things aren't generally recycled. fun side note these folks are going to make chef knives from laughing gas canisters found in london https://www.clementknives.com/
