getting the right spring

Right now I have a 1092 - 31/95 spring on my Ohlins shock.
I'm adding a Mori link.
The clevis is bottomed out making ride height as short as possible, but within range for my bike. I have 1/2 thread showing.
The preload adjuster and spanner lock nut are nearly topped out on the shock body, allowing 150mm compressed length of the spring.
I have the hydraulic preload adjuster set to nearly no preload pressure. 20 clicks total and I'm at 18-1/2 - 19 clicks out.

I think my goal here is to get a slightly shorter spring - a 1091, and increase the rate to 100 to accommodate the link.
Does this sound about right to your guys?

Good chance I'll be sending it to Kyle. I'm betting it's time for a service anyway, and he could put the right spring on then.

It only seems fair since I'm getting freshly blessed fork legs back from him too. right?

It sounds as though you have a spring that is on the heavy side for you JD, i would just fit the link and see how it rides :-)

I used SubSailors chart to figure this out.

https://www.rc51forums.com/forums/sho...s+spring+chart

According to the chart, my current spring should have a minimum of compressed measurement of 84mm? Is that including free sag and riders sag?

Quit making things 1000 times more difficult than they should be. A 1092 series spring is what should be installed on your shock. A 1091 series will work if a 1092 is not available.

Spring rates are listed by rider weight on the ROGUE site

^ I scoured all through the Mods page and read everything I could find on suspension and links. I saw that chart too.
I just got off the phone with Dan Kyle. He explained the basics of the shock and spring relation to me very well, I get it much better now.
After I recheck my free sag and riders sag numbers, I'm going to send the shock in for service, and maybe a new 100 spring, I'll let Dan decide.

My spring was waay stiff and the addition of the mori link softened it up nicely.

Did your before and after sag numbers change when you switched links?

I switched links today, and measured free sag and riders sag with both links.
The only change was 3mm more rider sag.
Whatever that may mean... if anything.
