Which AM wheel is this? The Traction wheels have 3/4" ID bearings and are pretty wide.

The Performance wheels or Plaction wheels are both narrower and have a 1.125 diameter bearing bore (bearing bore Performance wheel is a separate option from hex bore). You can use 1/2" or 3/8"ID bearings in these holes (The performance wheel is provided with 1/2" ID bearings).
