GiddayI'm puzzled a little bit by my Funduro rear shock mounting, the uppermost one, the composite rubber/steel bush job.  My first puzzlement relates to the fact that at the top end there's a bit of rubber around the bolt, yet at the bottom there's a sophisticated bearing. Why is that ?And second, what actually supports the top of the shock is it the bolt passing through the steel bush, or the proud ends of the bush being clamped to the frame via the torqued up bolt ? If it's the latter why does the bolt have to be a particularly snug fit in the bush, I would have thought a piece of number 8 would do the same job if it could be tensioned enough.
