I am just wondering why 57520 Technic Tread Sprocket Wheel Small is under the
Wheel Catagory? As I am trying to sort pieces I was trying to find where I had
posted this part and 99% of the time the parts are categorized by the first word
or the main part. I feel this should be categorized as a Technic part, not a
wheel. Especially since it is mostly used with other Technic parts.
This is just a suggestion, but if there is a specific reason, then I'd like
to know.
