[TheThinkTank] Wheel sizing system?

Hi all,

Katheryn from the Bike Kitchen in Windsor, Ontario here! Question for the community shop hive: does anyone have any ideas for effective and accurate systems for sizing wheels in your shop? We’ve got piles of used wheels with no markings or tires to identify them with that often get mislabelled (most commonly a 700c and 27x1 1/4 mixup) which is causing issues when we resell them.

Does your shop have a sizing system that is easy to use for students or volunteers without much technical knowledge to size and sort wheels with? Pictures would be appreciated if you’ve got a physical setup.

Thanks in advance!
