That would not work... In any way... Since the rear shock is mounted to the same part as the link to wich it's connected, with no real way of making the shock compress. It would just lock up the linkage. I could be wrong, but I don't think so
Look again!
1. The dark grey linkage is pulled down by the rear triangle. This compresses the shock from the top.
2. The red link only acts as a guide for the floating grey link.
3. The rear triangle moves upward and compresses the shock from the bottom as well. This differs from Brendog's bike.where as the bottom end of the shock is actually fixed to the front triangle above the BB and only gets compressed from the top.
Correct. The shock in the real pic is mounted to the front triangle above the BB. The pivot placements are also positioned slightly differently. other than that my drawing has pretty much the same concept.
