Suspension upgrade

Hi,
I'm getting a Wilbers rear shock installed, it's at the shop now.
I have got the height adjustment option. I am getting it set up for the maximum height.
I currently have the forks at 6 rings adjustment, and it steers and turns very quickly, without any instability, well, up to 170klicks or so.
So, my question is, with the shock height adjustment, does anyone have an opinion, or calculation, as to where the forks need to be set at, to get a similar steering angle etc with the new shock?

Why not start with the height set to be the same as the stock shock? This means you can do a comparison evaluation without any other factors influence.

Generally speaking;

25mm drop in front ride height equals a reduction in rake angle of approx 1 degree.

30mm rise (*) in rear ride height also equals a reduction in rake angle of approx 1 degree.

* measured vertically from rear axle.

So you need to take measurements before you remove old shock

Hi Glen. I have a stelvio shock on the bike. Before i put it on i was on the 5th ring at the front. The longer stelvio shock (its 10mm longer) raised the rear end 25mm. I rode around without changing the front for a couple of hundred miles, but found it pushed the front and took away that lovely natural steering the GRiSO has. So i have raised it back up to the first ring, about 20mm and it is back to its sweet self, but with a stronger spring and more ground clearance, perfect for me.

Ok, so i haven't made any measurements pre-dismantling
Looks like i might start with a similar setup to sidrat, and then adjust from there.

Let us know how you get on
