So if the bobbing sensation was less prone to happening with the elastomer in the suspension (as opposed to the nylon spacer), then possibly the next approach would be to install a very soft elastomer in the Mini's suspension. This would probably bottom out occasionally, but it might might reduce the bobbing on a smooth road.

Essentially, you have three mechanical systems (tire spring, suspension spring, seat post spring) and you are trying to get the oscillations to cancel each other as opposed to amplifying themselves. It's a tricky thing, but with enough playing around, I bet you can put the resonant above your preferred pedaling cadence.

I wonder, do people have trouble with the springy Brooks saddles giving pedal bounce?
