I have used them for years, wouldn't ride without them. Used to get a flat about every third ride, was ruining riding for me. Once I switched to airlocks, I can usually ride a whole season on a set. If I didn't weigh so much, I would be more concerned about the weight addition they bring, but the biggest improvement for me would be to lose weight. I can actually hear a leak start, and then hear them seal with the airlock goop.
Try them.
Cheers,
Michael
