What size do I need ?

Measure the diameter of your rear wheel outside the push rims (including them in the measurement), and going through the center of the wheel. 
If you are already using push rim covers, we highly recommend taking them off to measure, as their thickness might lead to an inaccurate measurement.

Then, refer to the table below :

The diameter of the wheel shown in the example below is 21", so the size to order is 24".
