So...I ordered a new transition gran mal frame and took a chance by going with the zoke roco rear shock instead of the dhx 5.0. the problem is that I hear it is a great shock but I know little about it. Transition suggested a 550lb spring but I've heard of other people who run the dhx on this frame and are my weight running a 350-400lb spring so 550 sounded high for the roco. I know the roco doesn't have a pedal platform like the dhx but would I need a 150-200lb heavier spring to compensate for that? anyone running this shock on a dh bike and what spring weight do you run. any info would be helpful before I order a spring.
