About this game

Enter chainring teeth, cassette cogs (comma-separated), wheel ETRTO in mm. Get for every cog: ratio (chainring/cog), gear inches (traditional unit from penny-farthing days), development in metres per crank rev, and resulting speed at your chosen cadence (40-100 rpm). Save complete setups - compact road, gravel 1x, MTB - and recall later. The Concepts tab explains gear ratio vs gear inches vs development vs gain ratio, Q-factor, cross-chaining, compact vs sub-compact.
