Would the dedicated 29er crown throw a fit if... WTB stepped up and began producing 650B tires and prebuilt wheels? WTB was one of, if not the first, to produce a true 29er MTB tire. Though they won't be able to be the first in this case, but it would definetely ruffle the feathers on the dedicated 29er crowd. WTB has grown to be a signifcant player in the MTB tire scene and their involvement with the 27.5" "bandwagon" could signal a new standard on the horizon.
Please don't read too much into this thought. I'm only speculating. But, what if?
IF WTB began to produce one 650B tire, which tread would you prefer?
