Univega Alpina Uno Mountain
 

Recently bought a pair of these bikes with the intention of flipping but have'nt been able to find much info on them in regards to value. Tange triple butted with spare spokes mounted on the chainstay, Exage parts including Biopace chainrings. I've attached a few pics of the smaller one.

$125 each in ready to ride condition, maybe $150 if you are in a hot market. Low end nutted rear axle rigid frame mountain bikes have very little value, but make a nice ride.
