I have the opportunity to pick this up for $60, I need another project so I'm leaning towards this one, question I have is, what's up with the 1" threaded? Also does anyone know what year this may be I won't have serial numbers until tomorrow. Also what would be decent upgrades for this bike? 2 reasons I'm doing this, I need a project bike for school next month and I like the frame. If anyone can help I would sure appreciate it. Thanks
