Largest bike manufacturer in the world does not make any 26″ bikes any more apart from 2 kids entry level models. The bulk of their range is 27.5″ and some higher end 29″ for the racing crowd.
Most customers coming into our shop are not concerned about 27.5″ its still a mountain bike, if they like the look of the bike and the price is right (it often is due to the manufacturer’s purchasing power) the customer is happy and soon out riding in the dirt.
When the largest manufacturer is focused on the mid size wheel, the rest of the market follows suit. Its neither good nor bad, its just a change in specification.
I ride a high end,carbon fibre race 29’er and can honestly say its the best mountain bike I’ve had, its incredibly quick yet huge fun to ride as it has a nimbleness that most would not associate with a 29’er.
Its not made by the largest manufacturer either. If the time came to get another FS I would be more than happy with 27.5/650
