Check out this article by Chris Kostman about what it takes to be a Classic Cyclist. Chris starts out like this:
Road Cyclists entering the sport over the past fifteen or so years have tended to come in by way of mountain biking, triathlon, or fitness, rather than pure road cycling. As a result, most of these “cyclists” lack the knowledge which makes up the foundation of the classic cyclists’ repertoire and which builds upon the backbone of the sport. Here are some things the classic cyclist knows and does.
And then he breaks it all down. Interesting reading for any cyclist. Thanks, Chris!
