That's the rumor, but I've never met anyone who had them fail catastrophically. I had a pair in the 90's and they held up to many years of Seattle bike messengering. I even T-boned a car and tacoed my frame, but the spinergy survived unscathed. I had to retire them when the brake surface wore through. I hear some versions were better than others.
