Stacking a Cafe Racer


I know it can be done, what size axle do I need?


M4 metric set screw. Make sure it’s long enough :slight_smile:


English please? haha I’m not sure what all that is.


It’s a headless screw(all threads) that is 4mm in diameter(I think) and they come in various lengths.

Most yoyos use a set screw for an axle.
