Statuses

The fix that occurs is to cut a proper keyway in the axle and hub bushing. There may be space for a disk brake too.

It could just as well failed by gouging a groove in the aluminium hub. This is terrible mechanical design. I hope it’s only an early example

One wheel spins freely because the D-hole in the washer has worn itself round. Damaging the thread while doing so.

Axle is smooth. Small flat on the retaining thread keys to a lugged washer. Single lug transfers all force to the wheel hub.

The Picador doesn’t seem to have a frame number. Unsure of age. Got one wheel off though. Shocked by what I found.
