I've tried searching the forum and still need help on choosing a decent aluminum frameset $1200 and under but, have not been successful. I rode a LOW// Tues. night and really liked the geometry and how light it was. He however had got the frame used for $750 in near perfect condition with no wait time. I have been looking at some more accesible frames for slightly cheaper and was wondering if they would be worth building over the Low. The bb17 Karma, All City Thunderdome and the new Cinelli Parallax. Any other sugesstions are most welcome. My experience with track bikes is limited to mostly my Bianchi Pista and an older Al Cannondale for a few short rides. I have taken the Pista on 100+ mile trips without any issues. I'm looking for a lighter, more high end fixed gear to have as a "do all" bike. Any help would be most appreciated.
