These wheels are only designed as landing wheels.  However they have saved many uprights and arms over the past few years.

What makes these wheels especially useful is that they can be fitted directly to a rigged glider.  (The hubs have to be fitted to the speed bar prior to rigging the glider.) 

The hubs can be left on the speed bar when packed.  (Sometimes a larger speed bar bag helps especially with hubs for aerofoil speed bars.)

These wheels are supplied with a bag so that dirt is contained within the bag rather than making the hang glider sail dirty.
