Started this summer with the "new and improved" Ride Now TPU's and now have several hundred miles on that bike with no punctures while riding. I did experience a single puncture when simply changing out tires and re inserting the tubes, a microscopic hole on the inside of the tube, from what I do not know. Personally I have never had great luck with Park glueless patches holding on standard butyl tubes but it sure worked like a charm on this TPU tube. I'm running them on my road bike, 30mm tires at 65 psi. I'm not convinced enough to tour with them but they are definitely faster on my road bike as they are only 36 grams and they have been proven to have less rolling resistance than butyl.
