29" is 622mm, the same as a 700c. 29" is just
made to mount fat tires.

The difference between 584mm/650b and 27.5"
is that the 27.5 frames are made to mount
wider tires,,, I think up to 3" wide?
Plus still have decent mud clearance on both
sides (1/2" or so).

Yeah, that's what I thought. Still, the move
from 584/650B to 622/700C for MTBs is very
sensible IMO. Even the girls are starting to
grow really tall these days!

So what is 27+ then, is that just another name
for 27.5"?
