Just found these recently.
The Rotacastor makes the stand very easy to move in any direction while being compact compared to normal swivel castors of the same size and load capacity.

Made in Brisbane using Rotacastors which is a Sydney company

Good stuff...I like how the wheels work.

Hmm .....wonder if they make those wheels big enough for my bike - ability to turn 90 degree instantly would be handy on the freeway most mornings
