I hope this post doesn't get modded "frivolous"...
Does anyone know the mechanics/electronics of the Bionx wheel sufficiently to say why the installation procedures insist that the notch in the axle be positioned at 6 o'clock?
With the help of a post from Chas Stevenson (thanks again Chas) I was able to get my dealer to return a Bionx wheel with a defective freewheel thread to the manufacturer for replacement. But another problem with this lemon was that I was never able to rotate the notch to the required position. I lined the semi-round jaws of a pair of a vise grip pliers with some 3/8" body-and-fender solder and gripped the axle tightly. It wouldn't budge.
