I have a Trek navigator thats almost a year old, I bought it to loose weight, and get in shape. I was 318 lbs when I first started riding, now Im 242 lbs, and I ride 15 miles a day. But today when I was takeing the bike out to ride I noticed a rubbing sound coming from the rear wheel. I lifted the bike off the ground and spun the real wheel, and when it gets to a certain spot the break moves and touches the wheel, only for a split second then the wheel moves fine again until it gets to that same spot again. Could this indicate an out of true wheel, and if it is could my heavy weight have caused it, if this is the problem could it also be considerd a warrenty issue?
Thanks,
Paul
