NINER TECHNOLOGY

For every model, whether it's their lightest cross country hardtail or the burliest full suspension bike, Niner consideres how each angle or length will interact with big wheels to affect the finished build.

View Details >

Niner believes that your alloy bike should incorporate all of the same high end features and technologies as any top of the line carbon bike. Niner uses the most current alloy shaping technology.

View Details >

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.
