The gravel category has reached an interesting, and perhaps inevitable, point in its evolution. What began as cycling's answer to the n-1 bike has gradually fractured into a collection of increasingly specialised subcategories. Riders are now routinely asked to choose between aerodynamic race bikes built for podiums and adventure rigs capable of disappearing into the wilderness for days at a time.
Take, for example, the evolution of the Specialized Crux. Once celebrated for its versatility and cyclocross roots, the latest version has evolved into something closer to a fat-tyred Tarmac, prioritising speed, efficiency and aerodynamics above all else. At the opposite end of the spectrum sit slacked-out bikes with suspension forks, mountain bike geometry and huge tyre clearances, to the point where they're often little more than hardtails with drop bars attached.
