Out of curiosity, how much did that build cost you? looks like a really nice bike, but I know fuck all about road bikes...
Well, I waited for parts to pop on craigslist that I wanted, then I would buy them.
I think I can go through most of it off the top of my head:
Wheels = $50 +$3 for 3 replacement spokes, craigslist
Tires = $25 each, wholesale
Tubes = $10 each, retail
Cassette & Chain = $40ish, retail hookup
Crankset & BB = $65, craigslist
Pedals = $80, wholesale
Bar Tape = $15, retail
Frame, Fork, and Seat post clamp = $120, Craigslist
Stem = $20
Bars = $25
Shifters = $135 for the set (Ultegra Rear and 105 Front), Craigslist
Derailleurs = $30 for the ultegra rear, $10 for the Dura-ace front
Seat Post = $100, retail
Headset = $50 retail
Seat = $80 wholesale
Cables = $20
Which would come out to about $900, but keep in mind I've been building this over two months, tires, tubes, stem, bars, pedals and seat I already had, and a lot of this stuff came with extras, so I have extra Front derailleurs now, and couple little nick nacks. I enjoyed meeting all the random roadies on CL most though.
Also, keep in mind that I may have spent $900, but there's a lot of parts on here way better than what you'd find on a $1600 ride.
