Well I finished building mine up this week too. I hadn't noticed the cable clash at the BB, so thanks for pointing that out Hexametilan. Mine did come with a Tange Prestige DB Cromo sticker on the seat tube, just above the Ritchey sticker that I see on your frame. I had an extra set of bottle bosses installed on the seat tube since it only came with room for one bottle.
My size large comes in at about 23# with front rack, pretty light I'd say. I haven't ridden it more than a mile or two but so far I'm happy with it. It definitely rides smaller than at 60cm bike, I'm 6'0" and it feels good.
