I generally pump up my tires before every ride as it seems to be a good flat-prevention measure. I use a floor pump w/ a gauge at home. I've got a Zefal frame pump for riding, but it's more of a backup since I usually reinflate with CO2. For extended touring, however, it would seem that a high-quality frame pump with built-in pressure gauge would be desirable. Can anyone recommend some good ones to check out? Bonus points for silver/polished aluminum color.
