Yeah sure, but his legs don't quite compare with Cipollini. How about figuring out the cadence in the small ring at 50 mph?

Walt "all in fun" Skrzypek ------------------------------------------ &gt; Actually, with a 53 chainring and an 11 cog, 50mph is

&gt;achieved at 130 rpm (assuming a 68cm diameter wheel, which is 26.8 inch or

&gt;2.23ft; circumference is then 7ft; 53/11 is a gear ratio of 4.8, so we get

&gt;33.6 ft/pedal revolution. Then 33.6ft/rev X 130 rev/min = 4368 ft/min =

&gt;0.83 miles/min = 49.8 mph). This is not surprising since racers often pedal

&gt;down mountain passes at such high speeds.
