    Very good alternative to 4" or 6" solid wheels.

    Very easy to adapt to existing frame.

    Good wheels for the price

    The wheels are good enough for indoor robots or light weight outdoor robots. I'm not sure how disable they'll be in the sun, but we're happy enough with them to have ordered a second batch!

    "Dimensions????"

    "I need to know the outside diameter of the inner ring of various bearings. The information will help in design of spacers on shafts. I also need to know the thickness of the hob measured parallel to the spin axis. That's for determining the length of screws that have to pass through the hosed provided for the likes of a sprocket. Where are the CAD or PDF machine drawings? The wheels are fine. It's the data on this web site that bothers me."

    Purchased Rubber Treaded Wheels

    The shipping prices for 2-day and faster deliveries were a bit high. Otherwise, my rating would be excellent.
