If you have a fixed gear bike you know how important it's to choose the right cog and chainring size. With Fixie Calculator it's possible to calculate the gear ratio (and therefore how hard will be and how much speed you'll be able to reach) and the skid patches (longer life for your tyres!).
Bugs fixed.
