All of the arguments against 29ers are basically down to how the rider can handle the extra bulk / weight associated with bigger wheels, and if you’re small then those arguments carry more weight. The debate is had for an ‘average’ rider of, say, 5’10 – 5’11 and the further you deviate from that average, the more or less a 29er makes sense.
I’m sure you can get a 29er to fit, but why do you feel the need to shoehorn yourself onto a big that’s possibly too big? Because they’re the latest fashion? Some notion that it’s gonna make you faster? The marketing boys have really got you wrapped around their fingers.
It seems silly to me. If you must go with a new* wheel size then surely 650b is better?
*yeah yeah, I know 650b has actually been around decades.
