Skid patch Calculator

There are several gear inch calculators on the internet, but most are either setup for geared bikes or only allow you to do one ring and cog size at a time. Since we're not in love with any of them we figured we'd design our own. If you're an ambidextrous skidder check the box on the left, and if you're looking for information on what each value actually means just click on any of the "i" boxes below. 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.
