And several other parts will likely come from a bike I bought for $100, mostly for its brand new Brooks B17. That CL purchase was completed by a local friend who was one town away from the seller. He kept the frameset, and I got all of the parts, including the B17, so I could imagine that I assign a value of $75 to the saddle and figure everything else cost me $25 (wheelset, crankset, brakes, bars, etc.)? And, finally, I have managed to amass items in the parts bin of which I have no idea as to origins; they likely came from geared bikes that I stripped down and sold off as single speeds. As I said, two values: estimated value and actual cost.
