The debate is still raging about the benefits of 27.5″ wheels (aka 650B) over 26″ or 29″. The forum banter and trail head smack talk is usually from riders without that much experience riding the different sizes. Bike Magazine has tried to make this a bit more scientific by using the same bike, the same trail, and same type of fork with two sets of ENVE wheels (one pair 26″ and the other 27.5″). The results are interesting. Even though I’m a shorter guy I think I’m less and less inclined to go after 650B. The differences really don’t seem to be enough to warrant the tweener size.
Check out what they have to say about their impressions of the size difference and their entertaining video below.
