NINER TECHNOLOGY

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

View Details >

Rather than just offering the same carbon products, Niner makes sure they are maximizing the benefits of the material so that their carbon products are purpose-built from the ground up.

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.
