Whats the actual on-road performance difference between the Giant Revolt Advanced Pro 1 and the Scott Addict Gravel 20, beyond the marketing hype of gravel-specific and aero-enhanced? Given the similarities in components and overall design, do the slightly different geometries and frame materials of these bikes really translate to a noticeable difference in ride quality, handling, and efficiency for the average rider, or is it just a case of diminishing returns for the price premium? Is the Scotts focus on road bike DNA and aero optimization really a hindrance in the dirt, or does the Giants more relaxed geometry and increased tire clearance actually result in a less efficient ride on paved roads?
