"victor" wrote clip)...How do you figue rpm?
^^^^^^^^^^^^^
Arithmetic. Measure your wheel diameter.* Multiply by pi to get
circumference. Divide into 5280 (feet per mile) to get wheel RPM. Divide
by your gear ratio (chainring teeth/cog teeth.
*Get this in feet. Measure in inches and divide by 12, or cm and divide by
30.48)
