You know, a few years ago I was convinced the MTB market was going to settle on one main wheel size that became mostly standard. Guess not though. I wonder if it will just continue fragmenting into different sizes or what? 26, 29er, 27.5, Fat bike, 29+... Is this just going to keep going or is one going to prove to be the king of the mountain? That said, 29+ seems like it might be a good mix of all of them and I could definitely building one up instead of a fat bike or 29er. I had written fat bikes off almost entirely until reading rvc's NASA themed build thread found in the Fat Bike section of Chinertown.
I'm definitely rambling at this point. Sorry, just some random thoughts
