The 27.5+ and 29+ size tires and bikes are new. Maybe everyone has not seen them yet. They are smalles than a fat bike and bigger than a mountain bike. 3 inches wide or there abouts.

I have been wanting a new bike for a while now, and am glad I waited. The new 148 mm rear hub should make a stronger wheel. All that extra air should add some cushion, and traction.

I would like to hear from some people who have tried both 27.5+ and 29+. What about full suspension and + size?
