A bicycle gear change mechanism includes a first gear including first teeth and a second gear including second teeth. Each of the first teeth includes a first surface and a second surface. The first surface defines a first pressure angle. The second surface defines a second pressure angle. The first pressure angle differs from the second pressure angle. Each of the second teeth includes a third surface and a fourth surface. The third surface defines a third pressure angle. The fourth surface defines a fourth pressure angle. The third pressure angle differs from the fourth pressure angle. The second gear engages the first gear.
