Gear Ratio & Skid Patch Calculator
Use our fixed-gear calculator to calculate your ideal gear ratio and skid patches. If you’re an ambidextrous skidder check the box next to the Wheel Size drop-down box. Select multiple rings and cog sizes for cross comparisons and don’t forget to choose a tire size if you want an accurate calculation of gear inches.
