59/59-180-150

Just received my used Wilbers shock. Seller said it was set up for a 185 pound rider. Spring is labeled "59/59-180-150"... don't know how to interpret that to RaceTech's recommendation of 17.28 kg/mm for my weight.

 

And to answer my own question, I just found this:

Newton meters - Kg/mm

Not sure if 150-180 means its a progressive rate or what, but it seems equivalent to 15.29-18.34 kg/mm and therefor right in my ballpark.

Spring diameter - spring rating - uncompressed spring rate
