Brave? Heck what is the parts list? I have values, but they are not what the op wants to hear about a Frankenstein bike.
all said I have my 80's Mercian all put together I spent about $200 and I know the op does not want to hear that.
So here is my Mercian with mostly Shimano 600 w/ xtr rear derailleur, branded Tange headset, Nitto stem, bbun-71, Mavic Reflex SUP Open pro rims, Concor saddle, newbaum's bartape, the bars are Winn Professional with some mar. Weighs about 22.5 lbs
Now the op Frankenstein bike about $300
