Sorry, Mike, I strongly hold the opposite opinion regarding valves for bicycles. Although I used to have Schraeders on the commuting/touring road bikes, I now use Prestas exclusively. I would not want to drill out my narrow road rims or even my heat-treated Ritchey mountain bike rims to accommodate Schraeders. I can pump more pressure into a Presta, lose less pressure per day from a Presta, and prefer the appearance of a Presta on anything other than a cruiser or StingRay bike. I carry a spare innertube, a small screw-on Schraeder adaptor (which I haven't used in years), and a convertible Zefal HP-X pump.
