  • Publication number: 20240067300
    Abstract: A bicycle sprocket for a sprocket cassette comprises a sprocket main body which extends about a virtual sprocket axis about which the sprocket is rotatable during intended operation on a bicycle. In the case of a single release tooth being formed, a release-side stabilizing tooth is arranged in the circumferential region of extent of an upshift recess formation. The release-side stabilizing tooth has an inner tooth contact surface which has a greater axial spacing to an axial reference position than an inner tooth contact surface of the reference tooth. Additionally, or alternatively, in the case of a single catch tooth being formed, a receiving-side stabilizing tooth is arranged in the circumferential region of extent of a downshift recess formation. The receiving-side stabilizing tooth has an inner tooth contact surface which has a greater axial spacing to the axial reference position than the inner tooth contact surface of the reference tooth.
