Well it happened to me the other day. still trying to figure out what happened. I knew my front tire was cupping cause when decellorating at 50 or so the handlebars shake back and forth. One time last summer riding in town,,30 mph I hit the front brake moderately and the handlebars nearly pulled out of my hands. well I forgot about that until thursday. I was following a garbage truck which I thought was going to pull into the same driveway I was heading into at about 35 mph and he stopped 100 yards early and it surprised me a bit and I stabbed the front brake. The next thing I new the handle bars cranked and I saw and heard the bike hit the pavement on its side and I knew I was next. I'm glad I was wearing gear, my helmet is junk along with my textile tourmaster jacket and boots. the footpeg broke off and the memphis fats and the cheap vinyl saddlebags held the bike up for the 10 ft. slide on the road. The left ankle hurts a lot but the doc says it will be alright. Would the alternate side cupping on the front tire cause it to pull one way or the other when braking hard? or is it my mistake for improper braking technique. I don't believe there was any sand or gravel on that part of the road but my thought was with the uneven tire surface area due to the cupping.
