What is the advantage of a 31.8mm clamp/handlebar bulge size over the old 26mm? My guess is strength, but are there any other known advantages? Are there more stem models available in the 26mm?

Thank you
The main advantage, as I understand it, is stiffness, which isbill

something a little different than strength. As for availability, a simple perusal of available stuff in catalogues says that anything over 26 mm is considered "oversized" and that less is available in the larger size.
I'm not at all sure that 31.8 mm is considered a standard size, so I would be sure to match sizes exactly. For that matter, you should be aware that all 26 mm systems are not created equal; some are a true 26, and some are 25.6 or 25.8, or whatever. While it doesn't seem as if such a small difference should make a difference, I think that it could, and, for both aesthetic and function reasons, you probably are best off matching bars and stems by manufacturer and even model line.
