Haha I think you now understand the situation. Still a great deal though.
I bought the giant for $100 AUD with mostly original kit on it, I had the wheels sitting around so thought I'd spice it up a bit.
I was a little curious why the donor bike with 7800 was so cheap but the lady had pictures of her racing it previously so it seemed fine and she just wanted rid of it. I missed out on getting a set of Spinergy 4 spoke wheels from her too which is a shame.
I am in the sticks a bit (southwest Western Australia) so not a huge market for older bikes like this down here.
In total this bike owes me $1225 AUD. Yep alloy rear stays and carbon main tubes. Pretty happy with how it rides too. Weighs bang on 9kg.
