Looks like someone has been shopping AZUSA…

thanks guys, yeah we got them from go-kart place. any ideas what they are for?
I would guess that the big one coupled with a small one could be used for some sort of arm joint.
Throwing at annoying freshman? 
actually I bet he got them from jackssmallengines… 
Um my best guess would be arm joints, don’t think you would have 3 different sized wheels…
