I have a Romic rear shock on my (new to me) K2 EVO 4.0. Downloaded the owners manual and attempted to determine which shock I have. Problem: The eye to eye distance I have (~214mm) does not match any of the listings on the ROMIC chart. Where do I go from here? I wanted to set this shock up based on my weight and riding style but until I know what's up with the eye to eye static distance I'm in a quandry. I did the test with the bike in a bike stand hence NO compression weight on the shock. I'm 165lbs and my spring is 450 x 2.5 but that's of little help until I know which shock I'm dealing with. (I originally posted this in the wrong location and "derby" told me there was a shock specific site-thanks derby.) 214 mm is close to 8-1/2inches but there is no shock of that length listed in the manual. Suggestions?

Eye to eye has nothing to due w/ tuning the shock. Measure the stroke of the shock. Measure the exposed piston shaft to the under side of the bottom out bumper (2.5" ?). Run 25-35% of the stroke to set the suspension sag. K2's came OEM w/ a 8.25" x 2" eye to eye shock for what its worth.

Thanks, but according to the first page of my ROMIC owner's manual there are seven different i 2 i shock lengths and it is necessary to identify which of those seven you are dealing with before attempting to adjust for sag. Each of the seven has a different stroke length hence a different initial sag measurement. What's confusing is mine doesn't match any of the seven.

Like I said sag is based on a percentage of the shock's stroke - simply measure yours. 8.5 x 2.5 is quite common. I had a 8.5 x 2.5 Romic on my Santa Cruz Bullit - ran 33% sag 2.5 / 33% = .825 @ the shock.
