I had these tubes mounted and inflated for a year, with occasional fills as needed. My vintage road bike was indoors sitting on a cradle in the living room and had a front blowout at midnight while I slept!! The bike was sitting by itself, had been inside all winter as a trainer, and not even used for a couple of days. The next day, I checked the rim strips, spokes, nipples, tire interior, and rims- everything was as it should be. A real mystery and thank goodness I wasnt on the road! I've had good luck in the past with Kenda products, and I like that they are mostly made in Taiwan rather than China, but this failure could have been bad.
Bought two of these tunes to resurrect an old 1980s Schwinn World Sport. Roughly 300 miles and tubes performing great. Hold air well without topping off to often. Price was great and bikes direct awesome as usual. Decided to order some spares for long rides
I HAVE NO PROBLEM WITH THIS PRODUCT, IT LAST IT CAN BE REPAIRD ON THE ROAD WITH MY PATCH KIT.I HAVE USED THIS BRAND FOR A LONG TIME ,AND I HAVE ALWAYS HAD GOOD SERVICS WITH THEIR TIRES &TUBES. I BUY OLD SCHWINN BIKES AND REPAIR THEM, IF NEW TUBES ARE NEEDED, I USE KENDA WHEN I CAN GET THEM.
