ProsIt works
Converted an old GT frame with 1 1/8 headset to a new stem and bars to amke it suitable for my son. Have to use both shims supplied, but it provides a secure fitting.

ProsIt just works
I have an old 1980's MTB which I've resurrected into my commuter. I needed to reposition the bars, but I could not find a suitable quill type stem. This thing opened up my options it grips solidly in the steerer tube and has allowed me to choose a suitable front loading ahead type stem.

Can you clarify the dimensions of this product. Is the max height of 90mm quoted, the distance from the min-insert line to the top of the stem? If so, the photograph does not seem consistent with this size. Thanks.

The dimensions for this product are incorrect, the maximum height should be 65mm.
