Turns out the spring rate is a bit TOO high for me (175lb, no riding gear on), as I get about 2mm static sag and 17mm laden sag. The difference between the two sag numbers is about right, so I may just need less preload, but it is already on the lightest setting for preload... :? Anyway, the rebound damping adjustment has very noticeable changes between settings, with #1 not even close, #2 almost enough and #3 just about perfect. I never tried #4, as #3 felt right after some bounce tests.
I have only one peeve about them (not bad, eh? ) - they did not build a left/right body set and this means that one rebound adjuster is on the outside as mounted on the bike and the other is on the inside. It is a PITA to move the inside facing adjuster and requires a screwdriver or pocket knife to make it work. That would be it so far.
Now to the ride. Given the high spring rate I was a bit worried about things, but they proved to be very well controlled and provide a nice plush ride with solid control. One rate softer springing would be perfect for me and would provide a great combination of ride quality and control. Given the spring rate, I have no complaints at all and they are actually significantly better than the OEM shock on my ZX-9. I prefer the ride firm over soft, so they should be fine after a bit of use. This was after riding some nasty pot-holed broken pavement on the shakedown ride, too.
So, I give them a 3 1/2 out of 4 overall, with 4 of 4 for quality, fit and performance. The only blemish is the left/right body issue. Without that, they would get a solid 4 of 4, especially for the price. For about $120USD more than Progressives you get adjustable rebound damping, a selection of spring rates and a rebuildable damper assembly. Worth it to me.
