Hi folks, I have a DHX Air 4.0 on my freeride bike I bought last summer. It's a single pivot frame, which means degressive characteristics. The Fox bottomed out often and did not have any mid-stroke damping. I opened the shock and filled the second main air chamber first with a piece of plastic, as it worked with silicone. Reduced Main Volume -> less pressure and more mid stroke. But it still bottomed hard. So I opened the piggy back and controlled the ifp- setting (internal floating piston). was about 33mm from the screwed cap. Removed the Cap and the ifp, filled in a bit of oil, and set the ifp to around 22 or 23 mm from end cap (which is 17mm high) (less volume, more progression). Fact is, it doesn't bottom out any more. Perfect progression. The stroke stops like 1-2mm before bottom out on big jumps. PERFECT! Mid stroke feels better, but I don't know if it's just because I spent so much work on it. ;-) I think Air shocks in general are a great addition to coil ones. But the manufacturers should offer smaller main air chambers and setup- changes without high pricing as accesoires/aftermarket items to give anyone the opportunity to get the characteristics they like. My DHX runs very nice since self-adjusting. So long ... Andy
