Is it possible that the pursuit of speed in custom gravel bike builds has become so singularly focused on optimizing components and aerodynamics that weve lost sight of the fact that a lighter, more compliant frame might actually be a hindrance to true speed on mixed-surface terrain? Or are we just so caught up in the gram and the desire to out-test each other on smooth, paved roads that weve forgotten what gravel riding is really all about - the ability to tackle whatever terrain comes our way with confidence and control? Would a custom gravel bike built around a decidedly un-optimized, yet incredibly robust, steel frame actually be faster in the long run?
