I went to the LBS today looking for a rerplacement mini pump. I found a Zefal Dually Alloy for 19.99. So I got it and what a little power house of a pump it is. It only takes 60 to 70 pumps to get my 700x28C tires up to 65 psi. It has a telescopic action. So you get double the air of a small mini-pump. Very nice pump IMO.
