I have a bike that I ride alot, and have had for many years, only ever had one flat, vintage cruiser though, maybe it has something to do with the rubber, as we all know, today's materials suck compaired to back in the day lol, I have a high end rocky mountain and everytime I ride it the stupid rear wheel gets a flat, so I gave up on that bike, spend alot on the thing and nothing but troubles, find a antique in the garbage, no troubles for years.
