Rear fork Rotation on F frame Moulton question
Does the through bolt rotate with forks or do the forks just rotate on the
I asked this question on the Yahoo Moulton Group but did not get any responses.
On the surface it seems like a dumb question but I am not sure. My guess is that axel rotates. Anyone know?
The axle rotates (unless it has seized). The axle is a rod threaded at both ends and captured with a serrated lockwasher and a nut at each end. If the axle were intended to rotate, Moulton wouldn't have used a lockwasher. There are two nylon bushings between the axle and the frame, which presumably is where the rotation occurs. In F-frames that have seized axles, the rear forks will rotate around the axle which can cause ovalized holes and resultant play in the rear suspension.

Responses are coming in on Yahoo, now too.
