K-set - The gears on the back of your bike. The ones you hope don’t

The gears on the back of your bike. The ones you hope don’t fall off while you’re trying to look cool.

My K-set fell off. I had to walk the rest of the way. Embarrassing.

I bought a new K-set. It’s still not as cool as my shoes.

I’m not afraid of anything. Except a broken K-set on a busy street.
