the above mentioned pumps are good, but they are not mini pumps (i wouldn't carry them in jersey pocket). unfortunately good mini pumps don't exist, but there are co2 cartridges, which are superior in most cases. fwiw i've got bontrager air rush small pump with co2 valve (good for it's versatility) and barbieri super-light mini pump (400 strokes to get the road tyre up to 85psi

). all small pumps are a compromise.
