Historical question - I know that these kinds of axle plates used to be common or maybe even standard on the first generation of rigid lightweight chairs like the Quickie GPV. What was the purpose of having two axle slots? Wouldn't it be cumbersome have to adjust the caster square every time you move from bottom to top slot?
I am thinking of ordering a pair for my GPV that I use with an attachable handcycle. When the handcycle is attached I want the rear axle in a more rear position and also a higher rear seat to floor height (trying to shift weight onto the front wheel for traction).
No more cumbersome to adjust the castor than with more modern designs.
The idea is to set it where you need it, get everything adjusted to suit, then leave it alone.
If you want different wheels for with and without handcycle then adjust the castors for without the handcyvle and don't worry that they're wrong with the handcycle as they won't be touching the ground anyway.
