Profile Racing – Tech Tip: Z-Coaster Support Bearing

This weeks tech tip from Profile Racing has arrived. This time around we get a short but sweet video from Matt Coplon where he explains why the Support Bearing on their Z-Coaster hub spins freely in the hub shell! Pretty interesting. Take a peek!

“While on the Maiden America Shop tour in 2017, a question was brought to our attention on the ZCoaster outer support bearing.

Why does that bearing spin inside the ZCoaster shell?
Is it supposed to do that?
And is that bad?

To answer your question, it’s part of the design and completely normal.
Here’s a quick tutorial. Let us know if this helps?”
