Pair (2) sets of wheel halves and hubs to make two landing wheels to fit on a round 1 1/8" speedbar.
These wheels are only designed as landing wheels. However they have saved many uprights and arms.
They are especially useful as they can be fitted 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.
These wheels are supplied with a bag so that dirt is contained within the bag rather than making the hang glider sail dirty.
