How could this test result have occurred?

That is a very good question. Our assumption is that a different setup was used in the tests we commissioned for the cranks prior to product launch. 

Various testing institutes – and we are talking about prestigious German testing institutes that are accredited and certified – perform tests of the same name, but unfortunately the conditions under which they are carried out are not uniform.

This creates a situation in which the same product can pass a test at one test institute but fail the same test at another. 

Test institutes and companies in the bicycle industry have been engaged in discussions for some time about how test standards can be made more precise and uniform.
