When I pass 29er's on either my 'cross bike or my 26" mountain bike, am I doing it wrong?
I didn't like the 29er I tested. I'm a smaller guy, so the geometry compromises get a little severe with the tiny frames. I could see how taller riders would really like a 29er.
The industry needs another wheel standard to generate more sales. Most of the same people that switched to 29 will switch to 650b and believe it better. That's how the industry stays alive.
