This allows fine adjustment of gear ratios to suit the conditions and maintain a consistent pedalling speed.

Cycling gear ratios. The 16 options give you a much more even progression through the gears. Racing cyclists often have gears with a small relative difference of around 7 to 10. Fundamentally a lower number of teeth on the chainrings results in an easier gear while conversely a lower number of teeth on the cassette provides more resistance and therefore a bigger gear.

A standard double set-up is usually the preferred choice for racing offering the largest chainring sizes for the. The calculator has now been updated to accommodate up to 12 speed rear.

If youre using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring and this number of teeth times the Schlumpf ratio for the second chainring.
