I'm pretty new (had my bike a month) & went for a 25 mile ride today for the first time at going that distance. Anyway, I took a course that had a lot of rolling hills. At one point, I looked at my speedometer and it said 26.2mph as I was coming down a hill. That made me start applying the brakes. LOL I'm trying to be less of a chicken but I do find myself lightly applying the brakes several times if I'm going downhill that fast.
