Dunno why people get so get-up about 650B, it predates 26″ by a considerable margin, it was the standard adult bike wheel size, being the standard European touring wheel, while 700C was/is the racing wheel. We only use 26″ because the Americans ‘invented’ mountain biking, and that was the size of wheel used on adult cruiser bikes. I had a bike with 650B wheels, or 27.5″x 1.5″, with Avon CX tyres, a Sturmy 3-speed, and chrome cow-horn bars, that I rode ‘dirt-tracking’ forty-odd years ago. It’s the best compromise for an average size rider for general riding, having a slightly bigger circumference allowing better rolling over rough surfaces, without the cumbersome effects of using wagon-wheels, which really only suit riders well over six foot. If I was buying a new bike now, I’d go 650B, without hesitation.
No voodoo about it, just common sense; a bigger wheel rolls better, but too big has it’s own issues.
26″ is a stupid size for a mountain bike wheel, quite frankly, we have the yanks to thank for that.

Yeah but if you re-read the question he didn’t ask for a history lesson with a bit of personal bias thrown in .
