Considering buying a new mountain bike, but am not sure which wheel size I want. I am leaning to 650b(27.5). I know a 29er would come in handy for the terrain here but I think I would prefer a lighter, more responsive wheel. (650b).
Which size did you pick and why?
Having owned both (and put over 1000 miles on each), I've come to this conclusion:
If you are tall, you'll probably prefer a 29'er. If you are under 6' or so, 27.5 will probably be a better way to go. Both are equally good for whatever amateur riders like us throw at them, and everything else is marketing hype. Bike geometry and fit is way more important than wheel size when it comes to what you'll be most comfortable on.
