Oh that is very very nice indeed and very well put together. Excellent choice in the CCDB. I have one on my similarly new Helius AM and it is absolutely every bit as good as people say; in all honesty I think that your experience of how good the bike is, is probably more down to the CCDB than anything else.
One thing I would say though is that I am really struggling to believe that it currently weighs 31.5lbs. My Helius is specced very similarly, but with Stans Flow rims and tubeless tyres. with the same fork, CCDB and a Ti spring but with lighter XT cranks and a 1×9 set up, its coming in at a shade over 33lbs; I'm probably saving about 1-2lbs with the lighter components and spring so that would mean the Tracer VP has to be over 3lbs lighter than the Helius AM, which weighs 3.1kg without damper.
I don't think it matters too much and it takes nothing away from your new bike, which is **** hot rod sledge!
So, to lighten it, I would say go for a lighter wheel set – depends on how heavy you are but maybe 819s or Stans Arch or the Flows which are a little heavier.
XTR cranks won't save much and will cost more than a decent set of wheels! Ti spring is an obvious place to loose around 400g for £150.
Have fun on it mate!
