Lezyne Micro Floor Drive High Volume (with Gauge) Pump (90 psi)This is our favourite pump to carry with you, whether you're commuting or touring remote South America. It's actually a miniature floor pump, with a fold out foot peg, and it has a long hose so you can reach your valve without getting right up against your bike. Plus it has a gauge so you can accurately measure the pressure. The high pressure version is great for narrower tyres, and the high volume version is ideal for wider tyres.
