"...One Gear to rule them all, One Gear to find them, One Gear to bring them all and in the darkness bind them..."
Very loosely taken from the Lord of the Rings, with apologies to Mr Tolkien, Gandalf, Frodo, and Middle Earthers' everywhere.
Gears were invented to make cycling better. They allow us to compensate for uphills, downhills, headwinds, steep and gnarly climbs and tired legs. Mountain biking without 27 gears is silly. It would show we have not evolved. It is stupid. It is hard. It is also fun, challenging and addicting.
Just like that Ring of Power, it kinda calls to you and whispers things into your ear. "Come to me and pedal. One gear is all you need. One gear of power. One gear of fun." Your friends will not hear it at first. As time goes by, some will join you on your quest. Some will never understand and as they see the hardened body, the far away look in your eyes and the spittle dried on your chin from the last heart crushing climb, they will be afraid. They will run away from the power of the One Gear.
But not you. You will hold it closely, keep it safe, keep it secret. The One Gear of Power.
