Front: 1300g - 70g lightweight tube - 95g skewer - 330g tire = 835g
Rear: 1570g => 1075g
Wheelset approx: 1910g
---- WEIGHT SUMMARY: 9,4 Kg or 9,2 Kg.. not sure exactly, I changed the wheels and it dropped to 9,2 Kg ----
Wheels: 1970g ... (Zipp 303 tubular, 1152g without skewers - would save 800g)

CUTTING IT DOWN (estimates):
So, upgrading seat (-200), brakes (-200), pedals (-100), skewers (-150) => 8550g
COST: 6.500 CZK = $350 for 650g
Next would be wheels (-800) and tires (-300) => 7450g
COST: 35.000 CZK = $1800 for 1100g
Crankset (-350), derailleurs (-150), seat post (-80) => 6850g
COST: 15.000 CZK = $750 for 600g
Handlebar (-100), stem (-50), cassete Recon (-150) => 6550g
COST: 7.000 CZK = $350 for 300g
Shifters Dura Ace (-120)
COST: 10.000 CZK = $500 for 120g (what a deal) => 6430g ... and that'd be the limit.
