I've been riding the same Vitus 979 about once a week the past 12 years. Very good condition when I got it. Bike is 20+ years old. It's had no problems, and always a pleasure to ride. I try to take good care of it. From what I've seen from other people about these bikes, a stress fracture in the aluminum is the problem to be alert for. I keep it dry and clean, no corrosion, and inspect while cleaning after rides. So far, all good. (knock knock).
