Each pre-assembled V-Wheel consists of four components:

Make sure everything is straight

It can be easy to accidentally press in a bearing crooked. Try your best to avoid this as you could damage a wheel this way.

The sound of success

If all goes well, you should here a satisfying ‘pop’ each time a bearing fits into the wheel.

Shimmy the shim

If the second bearing doesn’t seem to fit all the way into the wheel, its probably because the shim is misaligned. Use a small screwdriver to push the shim into the center of the wheel, and then push the bearing in the rest of the way.
