Levo Gen1 (Brose S) Linkage Calculation - under construction

stock shock: 197x48


new Link

I made a new link to let the rear wheel expand 18mm more (to fit the 170mm fork) and to achieve 12mm more travel.
The idea was to keep the stock shock, but due to the little oil volume of this shock I have had to service it too often.
Now I run a 200x57 Monarch plus (with reservoir) with the stock linkage,
