Описание (английский):

ISO 6699:2016 specifies the dimensions and tolerances to ensure secure assembly between the stem and the handlebar centre of a bicycle. It is applicable for bicycles intended for use on public roads, and on which the saddle can be adjusted to provide a saddle height of 635 mm or more. It is not applicable for specialized types of bicycle, such as tradesmen's delivery bicycles, tandems, toy bicycles and bicycles designed and equipped for use in sanctioned competitive events.

Overview

ISO 6699:2016 - "Cycles - Handlebar centre and stem dimensions" defines the dimensional interfaces and tolerances between a bicycle handlebar centre and the stem clamp to ensure a secure mechanical assembly. The standard applies to bicycles intended for use on public roads where the saddle can be set to a height of 635 mm or more, and excludes specialized types (e.g., tandems, toy bicycles, tradesmen’s delivery bikes and race-only machines). ISO 6699 helps manufacturers, designers and conformity assessors achieve reliable fit, interchangeability and safety at the stem/handlebar interface.

Key topics and requirements

Dimensional limits: The standard specifies common handlebar external diameters and matching stem clamp internal diameters (typical sizes include 22.2, 25.4, 26.0, 31.8 and 35.0 mm).

Tolerances and tabled values: Table 1 in ISO 6699 provides the acceptable dimensions and tolerances for these clamp interfaces to ensure proper fit and clamping action.

Measurement method: Stem clamp internal diameter can be checked using a tube of the corresponding external diameter to verify compliance.

Assembly conditions: Assembly must meet the requirements of ISO 4210-2:2015 (see clause 4.7) - including tightening the clamping bolt to the manufacturer’s recommended torque and verifying secure clamping under those conditions.

Manufacturing note: The standard recognizes certain manufacturing methods (e.g., hydroforming) may require alternative dimensional allowances; manufacturers should follow the guidance given for those processes.

Applications and who uses it

ISO 6699 is practical for:

Bicycle and component manufacturers (handlebars, stems) to design compatible, interchangeable products.

Product designers and mechanical engineers ensuring correct clamp fit and rider safety.

Quality control and inspection teams for dimensional verification during production.

Test laboratories and conformity assessors referencing assembly requirements in safety testing.

Purchasing and aftermarket parts suppliers to confirm compatibility across brands.

By standardizing the handlebar/stem interface, ISO 6699 reduces fitment failures, improves rider safety and simplifies aftermarket compatibility decisions.
