Thats a difficult one... this is my first 650B, and to be fair I'm super unfit and have only had 5 very short rides. I can tell you that it is incredibly surprising. Light, nimble, lively. The riding style, strengths and position are so completely different to a 29", especially something like the Wreckoning that just destroys anything you put in front of it. I think (for me anyway) you get lazy on a 29", its like free speed, as long as you stay off the brakes you don't really have to work the bike, it maintains its speed so well. The 650B on the other hand requires constant rider feedback, which sounds like a negative thing, but the catch is that it rewards you so greatly for it, that provided you have the fitness and strength to be "physical" all the time, I think it can be incredibly quick (and fun). I just need to build some serious strength endurance, and learn how to ride the small wheels. Maybe 26" for 2018...
