What size chainring do I need?

Classified hubs are optimised for 1X chainrings.

Classified is designed to be flexible, so you can tailor it to your own needs. As a general guide, we suggest you choose a chainring similar to your current big ring for the same size cassette. When in the reduction ratio, the Classified Powershift hub will mutiply your chainring size by 0.67. For a 50T chainring this means you will have the equivalent of a 34T virtual chainring when in the reduction ratio.


There are some limitations in chainring sizes in combination with different cassette sizes. Please check them here.


Please also observe compatibility with your crank and also check for the required clearances for the chain and chainrings for your frame manufacturer.
