It's Started already..

Interesting that it's only on the lower end bikes they have 27.5 wheels...

I think Nino Shurter is the only top XCO racer with 650b, though just look at the battle between him and Absalon on his 29er, nothing in it really betwen them...
A two horse race, those two are in their own league!

More bikes to buy in 2014 anyways, ya can never have enough bikes! :)
29 is the way for XC, 650b for Gravity Enduro etc. 26 for DH. 24" for ol fat ******* BMX and 20" for the the young bendy BMX ers. Surly have 29er+ already with the Krampus. As the reaction speed requirements get faster the wheel gets smaller.
Horses for courses and all that shizz nitt. Fill the quiver & do it all However this may be taking it too far http://www.youtube.com/watch?v=fYt6IqaHk_Q.
