These were flips back in 2008. Haven't since.

A 92 Nashbar MTB frame, paid: $0, sold $35. too small.
A 200x DiamondBack Sorrento frame and suspension fork: paid:$0, sold $75 too small.
A 93 Trek 850 frameset, paid:$0, sold $40. too big.
A 85 Trek 700 hybrid, paid: $20, sold $150. Overhauled, cleaned, touch up paint and a replacement Trek saddle. A bit on the large side (23"), otherwise I'd kept it.
A 86 Raleigh Technium 440, : $45, sold $100. Also a 23" frame. And I suspected the triangle was misaligned. And I had another big Technium race spec frame anyway. I wanted to keep it to build up as a tourer, but I was moving cross country. Too many bikes as is.
