That shock is sick, way cool. The bearing in the pre load adjuster, they come stock on the Ohlins TTX shock as well, a word of caution, it is exposed and will rust up almost immediately if you wash your bike. I tried keeping it greased, then it gets all gummy from the dust, not sure what the answer is.
The preload adjuster that KXpegger listed is available as an aftermarket product for Showa and KYB, recently saw it in one of the magazines.
Delphi, your going to have one sweet ride, that thing will last you forever.
