This graph doesn't make any sense. The wheel travel:shock travel is more/less a straight line. The shock rate is curvy. How are you defining shock rate? It's apparently not the derivative of the blue line because that should be really flatPut this together because I was bored I had to scale some of the pivot dimensions off of the pdf, so this may not be entirely accurate. It appears to have 110mm of travel for a 1.5" shock stroke. I'm not familiar enough with MTB shocks to know which tune would best suit this, but the graph should be enough for someone with knowledge to make a recommendation.
