So is the delta steerer a wet noodle then?
That might be a bit strong, but at first encounter it certainly doesn't seem to have the lateral stiffness of a standard round steerer. At least in comparison to the bikes in my inventory. Makes sense due to the dimensions. It should be good longitudinally, since it's full depth in that direction. I suspect it's designed to work best with either of the OEM stems and related spacers, and while it
will work with standard, non-integrated stems, you're going to lose some stiffness if you can't take advantage of the wider aero spacer interface. That will apply especially for folks running higher bars/more (round) spacers.
Still getting parts together for my build, so it remains to be seen how noticeable it is on the road, but when putting opposing force on the bars with bar/stem in roughly final position, you can easily see the uncut portion of the extended steer flexing laterally. Same bar stem combo as on my Aspero (Uno 3D/Easton EC90), so that's a known item. Marked difference between the two.
