Danson...I ran an elastomer -based 855 for a few years of intensive South Downs riding. It was excellent, both in the front and in the rear. The axle path meant very good small bump sensitivity and then the axle path giving extension of wheelbase as compression increased meant that they were brilliant downhill and on drops. The key thing was to run the elastomers with sag, which seems weird on a short travel bike, but was the secret to really making them work properly. I used Soft-Soft combinations on front and rear, and the bike shop I bought it from thought I was mad. But they, like many retailers, did not understand the principles of suspension. Imagine a car with no sag. That would = no grip. At 140lbs I am a bit flyweight, but that gave me about 25% sag. Which then meant that the suspension actually worked as suspension, rather than as violent bouncy springs - which was what most people complained of. Proflex did not do enough work with retailers or customers, to get the right sag into set up for each rider, and the reputation of elastomer based systems became poor, in error. Bob Girvin really knew his stuff, and the system really did work. But it required the right fettling and setup. The great thing was the ramp up, and no harsh bottoming out. With sag, they rode like things with twice the travel.
