As Fredly sez- it may be hard to read.
But I have the stem on test now.
Douglas, a bit of a critique for your blog tests…
After reading several of your pieces, it occurs to me that many of your entries could benefit from some recognizable “structure” that recurs with each piece tested. What do I mean? An example might be breaking the “test” reports down into blocks like form, function, installation and adjustment, short-term on road observations, long-term observations and/or final evaluation. You might come up with a different structure, but having one would help your readers navigate through your writings. We would more easily become familiar with your approach, and subsequent pieces would become more easily understandable.
Just a couple of stray pennies for thought…
That stem system is quite interesting, though. It isn’t completely obvious how the shim maintains steering alignment with the fork steerer tube. does it attach to the steerer tube in any way other than the top cap?
Yeah, I am still trying to figure all of this stuff out, and am in the process of reformatting everything.
The ATS shim is held on by the bung in the fork. Nothing else hold it on.
bump- this is too good to miss.

Other than the 80mm height of the shim, it looks to me like most other shims in that it has a relief channel that allows the clamping pressure from the stems fork clamp to secure both the shim and stem onto the forks steerer tube. I highly doubt the stems top cap which would be bolted to the star nut or internal compressor inside the steerer is all that is used to maintain steering alignment since those components are supposed to be used simply for the purpose of attaining headset bearing preload when installing the fork.
You are correct.
