A question about the edge with carts.. Isn't much better option the edge with no give when using carts?
I wonder how give can act with a cartridge that already has an inner spring... It comes to my mind some harleys that I see with rear shocks and the owner decides to install a seat with springs for an "old school" looking.
That could be the reason why Gaston decided to install a small amount of give of 1.8 or 2 mm. on the edge X, but I would like to ask to you the experienced builders if even that small give... Could not react in the opposite way with the cartridge spring?
