You've really got me wrong there TooTall. I actually WANT to find a 29er I like riding since I think that they are great for covering ground fast and these days I need all the help I can get… As I've said many times, I just don't want to compromise on enjoying the riding as a consequence but since I'm constantly being told that the latest 29ers are so much better than the older ones, I'll keep hoping that there is one out there that I like. I'll be riding one again in a couple of weeks to try yet again.
What I don't like is typical bike industry myths that become facts because it's endlessly repeated. I've only challenged the idea that 29ers are inherently a good choice for tall riders and I've yet to hear a convincing reason for it though I'll openly admit to wondering if there's some factor of the equation that I've missed since so many tall people seem to think they're a revelation though in the same breath I can't help but suspect that it's just because they look more in proportion.
The stability thing however sounds perfectly legit though I'd suggest it's because of the bigger wheels acting as a bigger gyroscope – the same as jumping with heavier wheels adds stability in the air – rather than because of the larger axle->bb measurement. I'm not certain that feeling more stable is inherently a good thing or not though.
