Addendum to my previous post. I sometimes take my '51 Raleigh Lenton with a SA AM 3-speed hub out on club rides and I do very well considering the lousy technology. As long as I am not with some racers or racer wannabes I can keep up all right. The deficiencies in my case are due to a lack of training for the last two years.
