tjodit said:Not that I'll ever be more than a recreational cyclist, but why then do all the top riders strive for a 100+ cadence? I've always thought it's because the legs will last longer that way...they can use an easier gear but since their cadence is so fast they still maintain their speed. Am I totally off base on this?

"Spinning at higher cadences reduces the watts-per-pedal-stroke, a measure of the force required to produce a given wattage. This makes the workload more tolerable for the muscles. Most experts believe that this is because fewer fast-twitch muscle fibers must be recruited to create the high torque levels required at low cadence. Pedaling with a too-low cadence increases reliance on fast twitch fibers, causing premature lactic acid accumulation, which makes your legs burn.
High-cadence pedaling works your cardiovascular system more, but reduces the relative intensity of the leg muscles. The key, then, is pedaling with enough cadence to keep your watts-per-pedal-stroke at a level that your muscles can handle, but at a cadence that will not overload your cardiovascular system. The optimal balance is different for every rider.
Each cyclist brings a unique set of genetics and training to the sport. The basic rules are, if your legs hurt more than your lungs, increase cadence. If your lungs hurt more than your legs, use a lower cadence.
If you decide that higher cadence pedaling might be more effective for you, now is the time to accustom your body to the different demands. Until you have learned the skills to pedal at very high cadence for long periods of time, you will be less efficient.
Give high-cadence time: If you decide that higher race cadence might work for you, understand that it may take months for your legs to develop the skills to create wattage efficiently at higher cadence. Cardiovascular conditioning also takes time to develop, so start well before the season and be patient."
