Calculates gear ratios for road and mountain bikes.
Bike Workshop calculates gear ratios for the road bike and the mountain bike. Select a pedaling cadence (RPM: pedal revolutions per minute) to calculate bike speed (km/h or mp/h) for a given gear and tire size combination. Bike Workshop allows you to calculate the pressure of any type of bicycle tire (mountain bike or road bike), on any kind of terrain and road surface.
