In another Q&A regarding some other part, it was ruled that anything not on the website was not considered legal.
How are recently discontinued products such as the V1 high strength gears (the webbing changed in v2) handled?
If they were considered not legal anymore due to being discontinued, then every single robot I've seen would have to rebuild with the new gears.

Green v1 gears and sprockets are legal for use, and can be considered an exception to the ruling posted above.
We will work to clarify this intent and distinction in future Game Manuals.
