Standards

A number of formal and industry standards exist for bicycle components to help make spare parts exchangeable and to maintain a minimum product safety.

The International Organization for Standardization
International Organization for Standardization
The International Organization for Standardization , widely known as ISO, is an international standard-setting body composed of representatives from various national standards organizations. Founded on February 23, 1947, the organization promulgates worldwide proprietary, industrial and commercial...

, ISO, has a special technical committee for cycles, TC149, that has the following scope: "Standardization in the field of cycles, their components and accessories with particular reference to terminology, testing methods and requirements for performance and safety, and interchangeability."

CEN

CEN may refer to:*Cen, or sen, is the currency of the fictional nation of Amestris of the anime/manga "Fullmetal Alchemist"As a three-letter acronym:* Cambridge Evening News, former name for the Cambridge News...

, European Committee for Standardisation, also has a specific Technical Committee, TC333, that defines European standards for cycles. Their mandate states that EN cycle standards shall harmonize with ISO standards. Some CEN cycle standards were developed before ISO published their standards, leading to strong European influences in this area. European cycle standards tend to describe minimum safety requirements, while ISO standards have historically harmonized parts geometry. The TC149 ISO bicycle committee, including the TC149/SC1 ("Cycles and major sub-assemblies") subcommittee, has published the following standards:
  • ISO 4210 Cycles—Safety requirements for bicycles
  • ISO 6692 Cycles—Marking of cycle components
  • ISO 6695 Cycles—Pedal axle and crank assembly with square end fitting—Assembly dimensions
  • ISO 6696 Cycles—Screw threads used in bottom bracket assemblies
  • ISO 6697 Cycles—Hubs and freewheels—Assembly dimensions
  • ISO 6698 Cycles—Screw threads used to assemble freewheels on bicycle hubs
  • ISO 6699 Cycles—Stem and handlebar bend—Assembly dimensions
  • ISO 6701 Cycles—External dimensions of spoke nipples
  • ISO 6742 Cycles—Lighting and retro-reflective devices—Photometric and physical requirements
  • ISO 8090 Cycles—Terminology (same as BS 6102-4)
  • ISO 8098 Cycles—Safety requirements for bicycles for young children
  • ISO 8488 Cycles—Screw threads used to assemble head fittings on bicycle forks
  • ISO 8562 Cycles—Stem wedge angle
  • ISO 10230 Cycles—Splined hub and sprocket—Mating dimensions
  • ISO 11243 Cycles—Luggage carriers for bicycles—Concepts, classification and testing


Other ISO Technical Committees have published various cycle relevant standards, for example:
  • ISO 5775
    ISO 5775
    ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation . It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously...
