This is why Tom Kuhn bearing yoyos used I size bearings, they are about the same diameter as a No Jive axle. Raider/ 720 bearings are K bearings slightly larger in diameter to I bearings but smaller than A bearings. I put 720 spacers and a K into a Spinstar and it can really shoot moons.

Replaced the transaxle with a Loop 720 axle, SPEC XS bearing and green 720 spacers (basically USA 720 guts). This Spinstar happens to be Zipline branded and laced with [kot-n]. STM for days with this setup. Great modern responsive plastic alternative, surprise @yyfben2.deactivated hasn’t issued these as Spinstar GTs. This was what I was talking about @AKYOYOMIKE [20200527\_162016] [20200527\_161915]
