1. The first picture used to describe the wheel was inaccurate. We received a wheel with 8 spokes.2. The wheel hub was about 2 inches instead of the 1 inch stated in the description. Although the wheel wasn't exactly what was advertised, we still got it working for a Roscoe 8 inch wheeled rollator. Had to buy a 4" bolt from the hardware store to offset the 2" wheel hub.
