Can you take the spacers from a pgm and put them on a Pro Fly?

Are you trying to make it un-responsive?

If so, you could but a new Yo-Yo, than keep the one you have now. Those Duncans don’t really do much unless you mod it. 🙂

I wouldn’t think so.

Profly uses a small bearing (not sure on the size) and the Plastic Grind Machine uses a size C, which is a lot bigger than Profly’s bearing. The spacers in the Plastic Grind Machine are made for size C bearings so they will NOT fit the ProFly without some modding.

the spacers in PGM’s can be flipped around to hold a small bearing :wink:
