Are these compatible with the H9? Also, are these for both front and rear wheels? And how many per wheel? Thanks.
Hi Bobby, thank you for your message. The bearing is compatible with all of our boards and the ones for the front and rear wheels are the same. You only need one bearing for each wheel.
