## What the source says

> Marketed as Flattop chain, these chains have a distinctive side plate design as well as rollers that are larger than typical bike chain. These SRAM 12-speed chains are proprietary and are not cross-compatible with other 12-speed components — they must be used in conjunction with the components they were designed for.
