I ride my bike to work everyday, a total of 10 miles to and fro. with other, regular tubes i was getting a flat about every 3-4 weeks, and getting really tired of that. I've now had a set of these tubes in my vittoria corsa tires for about three months, and ZERO flats. i was a bit skeptical at first, but these things have proven out. i'll never not ride these tubes going forward. yeah, they weigh more than regular tubes, but if you're the kind of dork that thinks he or she can determine the weight difference in grams whilst riding, then you don't deserve to ride these and be free of flats. just sayin'.
