Resulting RPM: Calculate RPM per gear at particular speed in 3 setups

If you want to know the RPM's at another speed, so not at the deafult '50', just enter that speed in the field 'Enter Custom speed':

The difference in percent (of course) still is 8.34, the absolute RPM difference in 3rd gear at 100 Km/h is 439 RPM.

If you want to experiment with your custom front and rear sprocket settings, just enter them in this table, they also will be entered (automatically) in the same fields at the top and at the lower part of the page. This way you do not have to scroll all the time. If you change them in the top or in the bottom of the page, the ones in this table will also be updated !

Next: Calculate Total chain length based on number of links
