This tool helps you measure your bike frame by giving you detailed instructions and a frame diagram showing you exactly what to measure. Once you know the frame size of your bike, you'll get a rider chart showing how tall a person should be to ride the bike. Link to this rider chart from your Craigslist or eBay listing to help buyers determine if they will fit the bike.
