New to the board, looks great! Anyway, I just bought an Iron Horse Quantum from Sports Auth. Was listed at $599, but talked the mgr into $299. Bike has Truvativ XFlow crank, Hayes M2 disc, front and rear, Rock Shox J1, shimano cassette and drivetrain and generally seems pretty well built. Has a nice upright feel to it. Anyone have any experience with these bikes. I think I read somewhere that its the same frame from one of their website bikes. Also, how would this bike stack up to a Trek 4900. Mine looks to have better components, but I'm just a novice.
