My Wilbers has landed too.
160 N/mm for the spring: 82 kg rider 50%, + 65 kg passenger 50%, sport, tour, road only.
Some paint imperfections near the spring ends, gladly they clocked it to hide imperfections when installed into the bike.
I'd also preferred a black knob for the hydr. preload.
Very good manufacturing, finishes and assembly, hope it will last.
