Sorry the Excel spreadsheet didn't copy and paste too well.
Rpm's are very important in cycling and if you see the difference it makes it might help you improve to become more efficient. Shift and use your fingers.
The front chain rings are 30 teeth, 42 teeth, 50 teeth and rear cogs are 11,12,13,14,16,18, 21,24,28 with an estimated wheel roll-out of 2050 mm.
If you look at the rpm 70 for a 50 -18 you get a speed of 14.85MPH, increase the rpm to 80 and your speed goes up to 16.98MPH, @ 90 rpm 19.10MPH, @ 100rpm 21.22MPH, the faster you turn your legs the more efficient you can be. This will take some adaption but really help you become a better and more efficient rider.
