Chainring Diameter by Tooth Count

Some bicycle frames have an upper limit for the maximum chainring size you can use due to clearance between the chainring and chainstay. We created the table and printable PDF below to help you determine how large of a chainring will physically fit on your bike. If you print out the PDF below at 100% scale, you can place the paper over your existing chainring to see where the paper contacts your frame.
