For several years now, the rumblings of this mysterious middle wheel size have been heard around the industry and ENVE has been listening. When you put the pros and cons of both 26 and 29 inch wheels and the associated limitations on frames, suspension, and ride quality on paper, the best of both worlds seems to lie somewhere in between.  When you put the unassuming 27.5 ( 650b) on dirt, all suspicions are confirmed.  Riders report faster acceleration/deceleration than his  29” brother, and better obstacle clearing and traction abilities than his 26” brother.  They say middle children are the most fun, ENVE might have to agree…
