Patent number: 11884363Abstract: An individual chain wheel for a bicycle front crank arrangement for engaging in a drive chain includes a plurality of teeth formed on a circumference of the chain wheel and having a first and a second group of teeth. The teeth of the second group of teeth are arranged in an alternating manner between the teeth of the first group of teeth. Each tooth has a load flank via which force is transmitted between an adjacent roller of the drive chain and the respective tooth. Each tooth of the first group may also have at least one profile with an opening in the vicinity of the flank, in which a portion of an inner link plate of the drive chain, which portion protrudes beyond the roller, engages.Type: GrantFiled: December 6, 2021Date of Patent: January 30, 2024Assignee: SRAM DEUTSCHLAND GmbHInventors: Markus Reiter, Joachim Hanke, Bryn Johnson, Andreas Vonend, Martin Kehrer, Henrik Braedt, Pedro Miguel Nunes Dos Santos, Luis Figueiredo, Rodrigo Antunes
