If you ride your bike to the top of the mountain,
And if you think “I am going to adjust my brake levers”
You should remember which way tightens.
And you should remember which way loosens.
Or else you will snap the bolt that holds on the brake lever.
Then you will be on top of the mountain with no front brakes.
And then you will be in a world of shit.
It was a hair-raising ride to the bottom of the mountain.
