Lezyne's ever-expanding accessories line now includes this combination pump that?s excellent for training or racing use, as long as your fingers don?t freeze.
The pump is a derivative of the slimline Road Drive, which is long enough to shunt a decent amount of air into your tyres without being such hard work that you can?t hit high pressures. It?s also slim enough to clip neatly into the supplied under-water-bottle bracket without adding too much drag to your down tube.
For really fast filling you can use the CO2 cartridge clipped onto the other side. This simply threads into the stainless steel extension hose of the pump, piercing itself in the process, and then inflating the tyre.
As the pump isn?t involved you can just use the cartridge and the hose for racing. You do need to beware frozen fingers with the bare CO2 cartridge though and the hose only works with screw-on valves, not push-fit extenders.
