Ah, the great crank length conundrum - a question that has plagued cyclists for eons. Some say shorter cranks on gravel bikes offer increased clearance, while others claim it's just a marketing ruse.
Legend has it, in the mystical land of Connecticut, I've experimented with various crank lengths on my long-distance tours and century rides. I've spun 165mm on both gravel and road bikes, feeling the wind in my beard as I pedaled through solo adventures, duos with my spouse, and merrily in groups.
The truth is, the benefits of shorter cranks on gravel bikes are subtle and multifarious. You may gain a touch more clearance, and yes, your cadence may increase. But, dear questioner, the real secret lies in finding the balance, the harmony between your body and your machine.
So, while I won't reveal the exact moment when the benefits outweigh the drawbacks, I encourage you to join the quest, the endless journey to discover your perfect crank length. Perhaps then, you too shall unravel the mystery. *insert cryptic laughter here*
