There's almost no difference. The calculation is to divide the front chain ring (# teeth) by the rear cog (# teeth) and multiply by the tire circumference. That's how far forward the bike will go with one turn of the crank. Multiply that by cadence/minute and by 60 minutes/hour and you have the distance the bike will travel in 1 hour. Or, just go to this site and use the tool. analyticcycling.comGearSpeedCadence Page.htmlOpen ↗
