all of the bending moment around the lower headset bearing is carried in the steerer inside the head tube. The lower headset bearing will not take up moment, that's what the upper headset bearing does. This stress is not insignificant, and steerers do have a history of breaking, including the one in the test.
Maybe more important... A couple posters thought that this should be reported to the moderators. Why? Really?
It was one poster. Since I'm a moderator, and Siu Blue Wind is a site administrator, it's obvious we know about your posts and would do something about it if we thought it was a problem.
