AIR 9 27.5+ 1-Star NX Complete Mountain Bike - 2018 by Niner
Outfitted with the trail-smoothing ability of voluminous 2. 8-inch tires, the Niner Air 9 27. 5+ 1-Star NX Complete Mountain Bike provides unparalleled traction and bump compliance for a hardtail lacking the sophisticated suspension of its full-squish brethren. It's a great choice if you regularly encounter rocky trails and root-latticed forest networks that would normally buck you silly on older hardtails lacking plus-sized tires and a longer 120-millimeter fork. Ultimately, the Air 9 27. 5+ is a solid upgrade if you're ditching your beat-up mountain bike from ten years prior or you're moving to more progressive trail geometry from a racier (i. e. stiffer and more uncomfortable) cross-country bike. Niner starts this build with a hydroformed aluminum frame that creates a lightweight ride with excellent trail feel. Using a multi-staged hydroforming process, a straight tube is butted and mechanically formed in preparation of the hydroforming process. Up next is multi-stage hydroforming, which is a series of molds used in sequence to create complex shapes. Multiple steps might take Niner longer, but they're able to reduce weight and achieve a higher strength. Hydroforming uses molds and fluid pressures to form metal tubes into shapes ideally suited for certain locations along the bike frame, meaning Niner can dial in the bike's riding characteristics exactly how they'd like. Besides using a hydroforming process to create a remarkably strong and relatively lightweight aluminum frame, the AIR 9 27. 5+ comes with more progressive trail geometry that's a sigh of relief if you're transitioning from an overly stiff and twitchy handling cross-country bike. Considering its head tube angle of 68 degrees, it'll handle the rough stuff with greater composure and descend confidently without trying to chuck you over the bars. However, it's still highly efficient at pedaling back uphill and covering large swaths of terrain, seeing it's not as slack as many of the trail bikes on ...
