Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 149, Cycles, Subcommittee SC 1, Cycles
and major sub-assemblies.
This second edition cancels and replaces the first edition (ISO 8090:1990), which has been technically
revised. The main changes compared to the previous edition are as follows:
— Terms and figures have been technically revised.
In addition to terms used in the two official ISO languages (English and French), this document gives the
equivalent terms in German, Italian, Dutch, Portuguese, Japanese, Chinese; these are published under
the responsibility of the member body for ISO and are given for information only. Only the terms and
definitions given in the official languages can be considered as ISO terms and definitions.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
This document has been developed in response to demand throughout the world for guidance on the
terminology used to describe the different parts of bicycles.
The aim is to encourage consistent and clear use of terminology, and hence to improve the safety of end
users by minimising the chances of any misunderstanding in technical communications.
The document aims to achieve this by providing suggested terminology for common bicycle parts in
many languages. The intention is to provide helpful guidance to anyone developing standards,
compiling product manuals or service instructions, or handling inventory or spare parts, by suggesting
easily understood terms which can be used for consistent, clear and unambiguous communication.
