I'm sure it works well but I would worry about what happens on harsh cornering with a load on board. The length of those cheek-plates to accommodate the elastomer height mean the plates will want to twist, will they not?Hi all
One of those ' wish I had though of that ? '
Adjustable by sliding bracket up and down chassis , so allows fine tuning , probably to much of a faff to do if load changes.
Could probably be made easy adjust if needed ?

Well the plate is thick enough for it to be tapped for the 4 mounting bolts ? so at least 4mm ? maybe 6mm and very short.
2 vertical flanges could easily be welded to the outside edges @ right angles to the plate so it is not show stopping ?
The question is can the pivot bolt be replaced with a driven half shaft ?

I wonder why you would be asking that?
It is not for a variable wheelbase , it is to fine tune the lever ratio to change the damping of the elastomer , probably no heavier than the jokes the bicycle world try to sell as ' shock absorbers ' ?

Then I'd slide the elastomer not the pivot. There's a lot more negatives doing it the other way round. I can not understand the choice to slide the pivot over the elastomer, hence my misunderstanding of the design.
Elastomers were used before suspension units on high end bikes. That was when suspension was crude. Decent suspension units came along and elastomers became the crude option. The big limitation of elastomer as suspension is it's lack of range requiring a high leverage ratio to give any substantial movement at the wheel. Using a high leverage ratio is a poor choice from an engineers perspective unless you are limited in the space you can find for the unit. Suspension specialists always try to get as big a movement at the unit as possible to give finer control.
Probably as good as cheapo suspension units though.
