New units in the foreground (sans springs), old units in the background, with springs. From this perspective it sure looks like Adreani is the original fork manufacturer for the HP2. Anyone know if that's true? Or is Adreani just another name for Marzocchi?
And here are the two units with springs, side by side.
If I was to guess I'd say the FastBike internals modify the BMW HP2 "light" version of the "Marzocchi Shivers" to *actual* Marzocchi Shivers. I'll ask David if that's what's going on.
Oh, and the springs are on the wrong side of the cartridges in those photos...
