Soulwood, that is a fabulous bike and you really did get a bargain, pretty much you paid cost price for it! I know you don't need to be reminded but this thing is handbuilt, by guys who spend five years training to be welders for Nicolai, even if they have previous experience. The thing is better aligned than a pair of train tracks and the bearings won't need any serious attention for years.
I've had two Nicolais and currently ride the AM (simply because I'm a fat b'stard and the AC/CC would probably not survive my 'Ton' like mass).
The only thing I would suggest is that, once you spent some time on the bike, seriously think about replacing the air damper. Those DT swiss cans are utter shite although they do weigh the square root of **** all. They have zero compression damping so you end up having to run a whole lot more pressure to get the thing to sit properly in its travel at which point the spring rate ends up being too high.
You're not going to notice that for a while though because you'll need to adjust your riding to suit having suspension and it's going to feel amazing to begin with. After time though, if something is niggling you about the bike, if it doesn't feel quite right and you can't put your finger on why, then the shock will be the reason.
Have fun and get yourself over to the MTBR Nicolai forum and introduce yourself.
