I ran down to the local swap meet yesterday and picked up a bike basket. However, I just can't figure out how in the world it attaches to my bike. The basket comes with 2 other components (minus screws etc.). One is a weird metal thing that has two holes (one is circle, and the other one looks like a werid triangle shape) and curves up at the end like an L bracket (with holes for two screws). The other component is some sort of support beam, it attaches to the underside of the basket and is basically a metal rod with two vertical, parallel, projections that both have holes for screws on them.
