There was a grove in the handlebar stem, but no key in the post, so the stem rotatated freely. Probably I needed to use the micro scew to get a rough fit before trying to set the bars, but my feeling was that that the tolerances on the set up were far too large and however effective the clamp there is always going to be a tendency for the bars to rock in the post.
