Thanks for the responses, and I didn't really look in the Fatigue Stresses.

But is this test not a bit too much? If probably a lot of steel lugged frames will fail? Our bikes have been touring around the world for about 20 yrs without any frame failures.

And the test was performed in the category city&trekking bike. (since we built trekking bikes)
But the loads for the category MTB are three times higher. (1200N instead of 450N)
