Gives innovative requirements and test methods applicable to any category of bicycle (city/trekking, MTB, young adult and racing) containing components manufactured, in part or whole, from composite materials.

The purpose of this Technical Report is to provide innovative requirements and test methods applicable to any category of bicycle (city/trekking, MTB, young adult and racing) containing components manufactured, in part or whole, from composite materials. Its aim is to provide technical solutions that reduce the risk of component failure and rider injury during the specified use of such bicycles. This Technical Report includes requirements and test methods validated by the bicycle industry and test houses for composite assemblies including forks, frames, wheels, saddle rails and seat posts. This Technical Report makes reference to current \'state of the art\' standards in the field of bicycles, agreed at CEN level through the publication of EN ISO 4210 series of standards. Therefore, the requirements and tests proposed in this Technical Report are intended to be read and applied in accordance with the appropriate EN ISO 4210 standard. NOTE Please note that the tests described in this TR refer in places to paragraph numbers from the applicable EN ISO 4210 series.
