The book "just ride" pretty much states my approach to cycling. The fact is that 99.999% of us are not professional riders, so why worry yourself about what they would do. Your ride today, tomorrow, or the next day is not a ride in the Tour in France. Just relax enjoy the ride, let your cadence spin at what ever feels right. Dont worry about what you wear, or what kind of bike you are riding. Adopt the attitude that I am riding for MY enjoyment and the heck with what anyone else thinks. Look at it logically. Your cadence should be what is comfortable for you not what some other person says it should be.
