2018 Niner AIR 9 3-Star GX Eagle Bike

If you are looking for one hardtail that can do it all for you, then the Niner Air 9 aluminum mountain bike will be a great option. This is a hardtail with the soul of a hardcore trail bike and the performance of a lightweight XC racer.

The frame has been made from hydroformed aluminum so that it can be kept light and durable with no wasted material to weigh you down. The responsive ride will encourage you to stomp on the pedals and practice your sprints off the line. But even if you don’t plan on taking this between the tape you will find a whole lot to get excited about. Its durability is equaled by its versatility so you can plan on taking this baby on long trekking adventures since it has Niner’s balanced geometry to offer a comfortable position where you can still get aggressive attacking your trails. They have included Boost 148 spacing to allow for greater tire/wheel options and more clearance. Add to that the fact that they have made the frame compatible to run either 29 inch wheels with 2.4 inch tires for crazy rollover, or 27.5 inch wheels with 3.0 inch tires with epic grip, and you can take on just about any sort of course except the most extreme DH trail. And since Niner has allowed for internal dropper post routing, you can even push this bike a little further in that direction.

This is really a hardtail that just is begging to please you and be the sort of bike you want it to be. Do you want a 1X, 2X or even singlespeed? You can set it up exactly as you like. Since they use a PF30 bottom bracket you can run either the standard press fit or spring for a single speed set up by using an eccentric bottom bracket. The frame has been designed around a 51mm fork offset which will give you nice, quick handling, while the max travel is set at 120mm. The post mount brakes can support up to 180mm diameter rotors so you can ensure some burly braking power.

With five sizes from which to choose, you’ll almost certainly be able to find the right match. The Niner Air 9 aluminum mountain bike will give you the top level performance that will encourage you to take this to the races while combining the comfort and versatility needed to be a great all-rounder for trail and XC riding.
