Niner is the only 29er-Only bike company. They do this one
thing, really well.  Learn More About Niner Technology   The
basic concept of the larger diameter is simple: it will keep
your wheels on top of oncoming obstacles. Rather than riding IN
the terrain, you’ll be riding ABOVE it, gaining more control and
stability on even the roughest trails. Think of the difference
between a skateboard wheel and monster truck tire. The
skateboard wheel can come to a grinding halt on a pebble while
the monster truck wheel can crush granny’s Oldsmobile. Yes, this
example is a little extreme, but you get the idea.  The larger
wheel offers increased rotational inertia, which in turn
improves the bike’s stability. The extra three inches also
increases the amount of tire contacting the ground at any one
moment, meaning enhanced tire bite. Dump a Niner into a corner
at full speeds and you’ll find that the unparalleled grip and
stability will hold to lean angles you never thought possible.
