This reads like a top shelf CX bike ready for racing. What's not to like about it? Only things you could nit pick are mostly personal preference items like saddle, bars and whether you need seatpost with setback. But you won't really know until you put it together and start the fitting process. If you have around $2300 (frameset) + $900 (wheels) + $1200 (groupset) + $45 (saddle) + $180 (bar) + $119 (stem) + $120 (post) + $85 (pedals) + $44 (tires) +$12 (tape) + $14 (barfly) = $5019, then go for it!
