How does endurance gravel differ from a touring bike?

Endurance gravel bikes are lighter, faster, and more versatile than traditional touring bikes. Touring bikes have even longer wheelbases, heavier-duty frames designed for heavy loads, and flat or trekking bars. Endurance gravel bikes use drop bars for multiple hand positions, are efficient enough for fast unladen riding, and can handle bikepacking loads without the weight penalty of a full touring frame. Think of endurance gravel as a touring-capable bike that is also fun to ride unladen, whereas a touring bike is optimized for loaded travel at the expense of unladen performance.
