Exclamation Ohlins rear spring decoder

this might be a good sticky!

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.

Good reference information

I am bumping this thread because it took me awhile to find it, again. I lost the original Dan K. jpg and needed to check something.


Some folks might like to have this information.

A poser in preparation.....

I have a question about the chart that was posted.

Can any body tell me what the numbers mean within the chart.

i.e I have a 1091-29 spring. So that has a spring rate of 90N/mm and a length of 160mm but what does the number 78 in the grid refer to? Is that the price, $78 ?
