Sorry to confuse. The SR stem is a 22.2mm - it's just that the quill part (i.e. the lower part which the bolt threads into) is a smaller diameter than the stem itself, by design. This means that it doesn't seat terribly well. Hence the creaking, presumably.
I've dug out all my spare stems and none of them is tall enough to get the bars where I need them. This is a slightly strange frame which is longer than it is tall, so I need a fair bit of seatpost and stem to make it fit me.
I did wonder about converting to threadless to give me more stem options, but it just looks wrong on a retro machine...
