I have been testing out different iterations of 650B prototype mountain bikes for the past 8 months or so and I will be the first to admit that I was a bit hesitant at first. That said, having gone back and forth between 26″ 27.5″ and 29″ for my “aggressive trail’ nature the middle option seems faster in pretty much every imaginable circumstance.

 

Here is a short POV video that I put together from a ride over the weekend. Fast and efficient on the ups, downs and everywhere in between.
