Overview
ISO 10230:1990 - "Cycles - Splined hub and sprocket - Mating dimensions" specifies the mating dimensions and tolerances for the sprocket and splines of a cycle hub. It applies to the hub of an internally geared hub or a backpedal (coaster) brake hub. Dimensions are given in millimetres and the required fitting geometry and tolerances are shown in the standard’s Figure 1.
Key topics and requirements
- Mating dimensions and tolerances for the sprocket-to-hub interface are defined to ensure correct fit and function.
- The standard provides the specific geometric features (splines and cut‑outs) and permissible variation for manufacturing and assembly.
- Reference to geometric tolerancing rules: the meanings of tolerance symbols are given with reference to ISO 1101:1983 (geometrical tolerancing) and the maximum material principle referenced in the document (as cited within ISO 10230).
- Dimensions are presented in millimetres and the standard specifies the required form and positional tolerances relevant to the spline-sprocket assembly.
- Figure 1 in the standard contains the authoritative dimensional drawings for the mating parts; users must consult that figure for exact values and tolerances.
Practical applications
ISO 10230:1990 is intended for professionals involved in the design, manufacture, inspection and maintenance of bicycle hubs and sprockets:
- Bicycle component designers - to ensure interoperable spline/sprocket geometry when specifying internally geared or backpedal brake hubs.
- Manufacturers and suppliers - to produce sprockets and hubs that fit reliably and meet international tolerancing expectations.
- Quality engineers and inspectors - to verify dimensional conformance against the standard’s tolerances during incoming inspection and final QA.
- Aftermarket part makers and repair services - to develop replacement sprockets that correctly mate with existing hub standards, reducing fitment issues and service failures.
Related standards
- ISO 1101:1983 - referenced for meanings of geometric tolerance symbols.
- Geometric tolerancing principles referenced in ISO 10230 align with the maximum material principle cited in the standard (see referenced geometric tolerancing documents in the ISO text).
By using ISO 10230:1990 as a design and inspection reference, bicycle makers and service providers can achieve consistent spline/sprocket compatibility, reduce assembly problems, and improve long‑term reliability of internally geared and backpedal brake hubs.

Foreword
IS0 (the international Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electr-otechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Interna-
tional Standard requires approval by at least 75 % of the member bodies
casting a vote.
International Standard IS0 10230 was prepared by Technical Committee
ISO/TC 149, Cycles.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d’organisme, s nationaux de normalisation (comités membres
de I’ISO). L’élaboration des Normes internationales est en générai
confiée aux comités techniques de I’ISO. Chaque comité membre inté-
ressé par une étude a le droit de faire partie du comité technique créé
à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO participent également aux tra-
vaux. L’ISO collabore étroitement avec la Commission électrotechnique
internationale (CEI) en ce qui concerne la normalisation électrotech-
nique.
Les projets de Normes internationales adoptes par les comités techni-
ques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins
des comités membres votants.
La Norme internationale ISO 10230 a été élaborée par le comité techni-
que ISO/TC ‘l49, Cycles.
