Ok, your brakes are lighter + integrated shifters. Wheelset... is that significantly lighter than mine?

I bet our bars are about the same, then my seatpost is lighter (bontrager CF.) Are you counting the saddle bag?

Including all that XTR, I'm wondering if 1.5lbs for like a grand is really worth it. That's not much weight. lol What do you have into that bike? about $4,000?
