This is not good. So it appears that the author is attempting to 'pidgeon hole' 27.5" wheeled bikes as the short guys 29er. That would be a real shame, and is total BS.
OK, i read further...I feel better with this statement:
“In a few years it will be the most popular wheel size,” commented David Turner, owner of Turner Bikes, “and (27.5) will pull duty in everything from downhill to cross-country, but on a bell-curve scale. It will see it most use in the trail bike market and less on the other ends.”
