Well, you said that the stem measures "exactly 1 inch" in the place where you want to clamp on the shifters... is that correct?
In that case you want a 1 inch clamp (which may not exist, since these shifters were originally meant to go on a downtube). Or you could buy this 1-1/8" size... and make a shim using a thick piece of rubber wrapped around the stem. A shim can work very well, and though it may make your bike look goofy... oh wait, your bike is already going to look goofy with stem shifters
