1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can “decode” what you are looking at.
• The 1091 refers to the diameter and the length of the spring. Almost all Ohlins springs have a diameter of 57mm so that’s easy, the 1091 in this case means it has a 160mm length (when not on the shock)
• The -34 is the spring rate. For some unknown reason Ohlins uses it’s own numbers to label rate, but below on the rate conversion chart you can cross reference this number. In this case a -34 is a 100nm or 10.19kg or 571lb spring
• The /100 is the springs rate in Newton meters, but without the decimal. In this case the /100 means it’s a 100nm spring.

Ohlins Shock Spring Chart
The blue spring will not compress any further until the applied load on the green spring reaches the blue spring's preload. So, initially, the spring rate will be the same as the green spring's rate. Once the total load is greater than the blue spring's preload, the red coupler will come off the yellow locking ring and both springs will be active.
