My favourite regular ride is 16 years old. Until I hurt my back, I used it regularly for competition. Until 1999, my duthalon, triathlon and time trial bicycle was a stock 1974 friction shifting 10-speed modified only by the addition of aero bars, a wheel cover. and a computer (which was a 1st generation Cateye computer that my competitors jokingly referred to as a "laptop" due its enormous size relative to their "postage stamps".)
