Multi-pinion arrangement and bicycle drive having a multi-pinion arrangement of said type

A bicycle drive comprising:

• a multi-sprocket arrangement for rotatable mounting on a rear-wheel axle an engagement with a bicycle chain having inner link plate pairs and chain outer link plate pairs, comprising:
• a sprocket having, between an axial inner side and an oppositely situated axial outer side, a flat sprocket body and a plurality of teeth formed on a circumference of the sprocket, the plurality of teeth comprising:
• at least one tooth of a first tooth group, the axial width of which is dimensioned to be greater than a chain inner link plate spacing and smaller than a chain outer link plate spacing, and
• a second tooth group, the axial width of which are dimensioned to be smaller than the chain inner link plate spacing,
• wherein, when viewed in a circumferential direction, at least one sequence of three teeth is provided in which a tooth of the second tooth group, a tooth of the first tooth group and another tooth of the second tooth group are arranged directly in succession, and at least the one tooth of the first tooth group has a projection in an axial direction, which is produced by a material deformation;
• a rear gear shift mechanism,
• exactly one front chain ring arrangement with at least one chain ring 3;
• and
• a bicycle chain configured to engage with the chain ring and with the sprocket of the multi-sprocket arrangement.

A sprocket for use in a multi-sprocket assembly attachable to a rear wheel of a bicycle, the sprocket comprising

• a flat sprocket body, the sprocket body comprising an attachment portion configured for attachment to at least one other sprocket of the multi-sprocket assembly, and
• a plurality of teeth formed on a circumference of the sprocket body, the plurality of teeth comprising:
• at least one tooth of a first tooth group, the axial width of which is dimensioned to be greater than a chain inner link plate spacing and smaller than a chain outer link plate spacing, and
• a second tooth group, the axial width of which are dimensioned to be smaller than the chain inner link plate spacing,
• wherein, when viewed in a circumferential direction, at least one sequence of three teeth is provided in which a tooth of the second tooth group, a tooth of the first tooth group and another tooth of the second tooth group are arranged directly in succession, and at least the one tooth of the first tooth group has a projection in an axial direction, which is produced by a material deformation.
