The purpose of PD CEN/TR 17653 is to provide innovative requirements and test methods applicable to any components and assemblies of any category of bicycles (city, trekking, MTB, young adult and racing). PD CEN/TR 17653 aims to provide technical solutions that reduce the risk of component failure and rider injury during the specified use of such bicycles.
PD CEN/TR 17653 refers to current “state of the art” standards in the field of bicycles, agreed at CEN level through the publication of the EN ISO 4210 series of standards. Therefore, the requirements and tests proposed in PD CEN/TR 17653 are intended to be read and applied in accordance with the appropriate EN ISO 4210 standard.
PD CEN/TR 17653 on components and assemblies used in bicycles — innovative requirements and test methods is useful for:
There has been some concern in the development of composite wheels (tubular or clincher rims) that excessive heat generated during extreme braking (long decents or turning during decents) can cause material damage that may lead to structural damage of the rim. PD CEN/TR 17653 provides wheel impact test that will help you improve the quality of the wheels.
Mudguard constructions that comply with the current test standard can still cause unsafe situations in case of obstructions. The obstruction can deform the mudguard (stays) which can result in front wheel blockage. With the new test method described in PD CEN/TR 17653 the chance of wheel blockage due to unsafe mudguard constructions will decline significantly.
PD CEN/TR 17653 provides technical solutions that reduce the risk of component failure and rider injury during the specified use of bicycles.
