00:00Did you know that bicycle brakes used to be dangerous?
00:02In the 1940s, the brake pads pressed directly against the tire and breaking down the rubber.
00:07And on wet surfaces, you simply couldn't stop.
00:10Skidding was inevitable.
00:11In the 1950s, they redesigned everything.
00:14The brake pads stopped touching the tire and began pressing against the sides of the metal rim.
00:18That change is exactly the reason why today you can brake without falling flat on your face.
