I run a 29er with Ralph's Shwalbe (evo, skinny, light tires). I got a bite from a sharp rock a few weeks ago. The Stans wouldn't seal it. I put the phone on and walked on. The tire was fairly new and I really didn't want to leave a tube in it. I searched the internet for a tire patch and found this one. I've used many stubs in other tires (car tires, lawn mowers, etc.) and have had great luck. Because of the price, I decided to try them. I removed my tube, added some racks, pumped up the tireโฆ
