Messingschlager PartFinder

Part Finder

The Messingschlager PartFinder is more than just a classification matrix – it is your trusted guide in the world of bicycles and bike components.

Based on the internationally recognized ASTM F2043-13 standard (ASTM = American Society for Testing and Materials), it clearly categorizes bikes and components according to their intended use. At the same time, it defines quality standards and testing protocols that go beyond the common ISO 4210 / EN 15194 regulations.

Developed in close collaboration with independent, accredited testing institutes, the PartFinder stands for absolute safety, transparency, and top-level quality. The mission is clear: to offer dealers and end consumers a simple, reliable guide so that everyone can quickly and confidently find the right, tested component for their specific needs.

Every bike and component is designed for a particular type of use. Loads and stresses vary widely – from urban everyday riding to extreme off-road conditions. Thanks to intuitive pictograms, finding the right part is effortless!
