R6 rear shock in process of build. Spring arrives today along with preload collar and shim. How many clicks are you running on the rebound adjuster? I'm 225 in gear
The rebound setting has 25 clicks total. Minimum setting is 25 clicks out, standard setting is 9 clicks out, max is 1 click out. Turn counterclockwise to increase. I weigh 190 without gear. I set the rebound at midway, 12 clicks out, and it seems about right to me.
No recommendation on initial settings but just wanted to say a couple clicks does make a noticable difference. Unlike some shocks I have had. So there should be plenty of adjustment if the spring is in the ball park.
