I purchased this recently from craigslist. It needs a few minor parts and a good scrubbing/teardown but overall it looks to be in good shape. It doesn't say SE or GT like some Magnums but it is double butted chromoly. I do like the Sugino crank, I'm not sure if the drillium was stock or not but it makes the bike for me. It is a 58cm from middle of bottom bracket to top of seatpost, 55.5cm to the middle of the top bar. I am also testing my new Park Tool PCS-9 repair stand.
Components are Suntour downtube shifters, Suntour VX front and rear derailleur, Diacompe brakes with more modern tektro brake levers/hoods, Suzue hubs and some aluminum 27" x 1 1/8" (I believe) wheels and a suntour freewheel.
The bottom bracket is 'catching' as I turn the crank. It can turn completely but it catches at various points and it does not spin freely. I will disassemble it and see what is up. The stem also moves from side to side ok, but as soon as it reaches a certain point in the rotation (usually nearer the end point when the handlebars could hit the top bar) it becomes quite difficult to turn. Any ideas? I am going to tear apart the stem/headset and redo the bearings but I am not sure if this is indicative of a bigger issue.
