Ok, so we're on a short ride yesterday, stop to stretch for a minute, while standing at the back of the bike I see a bump in the middle of my drive belt. I think oh crap I have a rock under the belt. So my friends and I roll it forward to get the rock out, and there is no rock. Just a bump in the belt. I wish I had taken a picture, but it reminded me of like a steel belt breaking in a tire and causing a blister or knot. Has anyone experienced this ? I will take it to the shop Wednesday and have them check it out, but I was just wondering if I was the only one ?
