What can anyone tell me about this unit, I'm assuming it's rear shock preload (I don't think it's that, as the collar would do that); spring rate; rebound rate? There appears to be two adjustments possible according to the embossed lettering around the nut and screw head, low speed and high speed. Also, it's nitrogen charged according to the label on the end.
It handles great for me now, so I'm not intending to monkey with something that's fine, just curiosity is getting to me.
