I normally use 'livelier' shocks like Romic and Fox but I was wondering how good or bad would a 5th Element work on a frame that has a progressive design. I would probably set it up in a way that would keep the shock really active through the first 3/4 of it's stroke and then ramp up. I remember having one on a 2003 BB7 and it felt pretty good. It felt kinda harsh just sitting on the bike but once you got some speed it seemed to float over everything (of course that's using a linear frame). Second, because of the air chamber and air volume adjust, if I normally run a 500lbs coil, what's the equivalent for a 5E?
