Cube Kathmandu - adjustable stem, but how?

[AlanW]

So today my wife finally collected her new Cube Kathmandu SLX750 and very nice it is too!

Just doing some fine tuning to her riding position and the need to lower the angle of the stem down a touch. I was assuming that as there are two Allen bolts in the stem it would just be a case of undoing said bolts, adjusting the angle and then retightening the two Allen screws again....wrong!

I've undone the both the Allen screws (actually removed the lower one altogether) and it still refusing to move, so before I doing something I probably shouldn't, I thought it best to seek advice first.

Any suggestions as to what Im doing wrong please?

Are there two cap screws that tighten into the stem bolt? If so, loosen them, adjust bars and re tighten.

Some stems has an extra bolt below, under the stem.
