Fat tubed bikes just look over built and over weight even if in fact they are really lightweight and hi tech like Dales. The GT fat tubed bikes look especially over done when other manufacturers can get the same performance with less lardy looks. Steel GT's are nice though as they have skinny tubes. Its just aesthetics nothing more
BITD I hated steel tubed bikes, alu all the way. Steel looked to roady and mtb'in embraced new technology which was part of the appeal of the bikes the cannondales/manitou/san an/Klein
etc. Now its almost inverse where the ride and looks of steel trump the fat ally most
of the time.
other way round, loved steel hated Al, now can see the appeal of the coke can bikes but will always love a steel frame most (just as long as it does not have a u-brake!
"Aesthetics", a view I didn't think you held in any high regard velo?
