NINER TECHNOLOGY

Because the lower swingarm linkage is located underneath the bottom bracket, chain torque in any chainring effectively neutralizes the unwanted forces that degrade power transfer to the rear wheel.

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.

PRODUCT DESCRIPTION

Niner JET 9 Frame 12x142mm Through Axle

Life is complicated enough from nine to five, what you do in your off hours should be simple – it’s time to hit the trail on the new Jet 9. Enter your first mountain bike race, visit that MTB mecca or just crush souls on the after-work ride. It’s the simple action of “doing” that’s important and that is why Niner created the Jet 9.

Serious good looks, new lighter weight, more CVA travel, the Jet 9 has all the technical refinements that define an XC dominator. Carbon wonderbikes are great, but you’ll appreciate the technologies that Niner utilizes in their alloy frames, too. They are dream bikes within reach – Airformed alloy with as many custom details as our RDO line, something you can log big miles on, day in and out. Sound like a bike that you might want in the garage? Us too!
