I'd like to compare what others with the Wilbers shocks have been given for spring rates, because after yesterday, I'm almost certain they've given me a spring that is a bit soft. I've got printed on the spring 59/59-45-165. I think this equates to a 45nm/mm spring, which is about 256ft/lbs, or 4.5 kg. I've got the preload wound up by almost half of the threaded section and that is giving me 40mm of preload, which on a 73mm travel spring is too much I think. I'd be happier with 30, but if the spring rate is correct it shouldn't need to be wound up that much. It's also bottoming out a tad too easily. I know for sure that this spring won't cope with a passenger. What have others got printed on their springs? How do others feel about the spring rate?
