How do you define "cyclists," and how did you arrive at your 99% number? I think of cyclist as a person who rides a bicycle. I see a lot of people riding old bicycles, certainly more than 1% of cyclists. Maybe you're limiting your definition to people who ride for fitness and have a minimum level of speed, strength, etc. We have a lot of bike commuters here in NYC. They ride old bikes, and they are not trying to improve their times by studying training techniques or by improving their equipment.
