At this point in bicycle evolution, finding a bike
without a sloping top tube is probably a fool’s errand. For the original intention of using bikepacking bags for off-road use, few modern (post about 1995) mountain bikes have horizontal top tubes for rather obvious reasons. Not many road bikes have horizontal top tubes any more as well. Road bikes have sloping top tubes for performance reasons.
