Schrader vs Presta
I asked this same question on another forum with similar results. One of the answers I got was that you can't find Presta at a loca Wal Mart if you are out touring. And I can't argue with that but if you are running a 1 1/2 inch tire on a 26" wheel you are going to have problems finding these. I have drilled out my mtb tires to schrader and have left my T2000 presta. I guess the debate goes on.
