Today's full-suspension frames are pretty good, but nothing quite matches the efficiency and weight savings of a hardtail. If you're looking for a worthy racing partner or something for long trail rides in the backcountry, Niner's AIR 9 29 2-Star is worth a look. It provides the excellent rollover of 29-inch wheels and modern geometry so you can spend time riding your bike instead of wrenching on shocks, pivots, and the like. Built up with a dependable kit, this bike is chock full of value and makes for an exceptional first bike or if you're looking to step up your ride or add another one to the stable. Niner starts this build with a hydroformed aluminum frame for a lightweight ride with excellent trail feel. Using a multi-stage hydroforming process, a straight gauge tube is butted and mechanically formed in preparation for 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 longer but Niner is able to reduce weight and achieve higher strength. Hydroforming utilizes molds and fluid pressure to form metal tubes into the shapes best suited to the locations on the bike. These molds are created to the desired end shape, and tubes are placed in them while high-pressure hydraulic fluid is pumped in causing the tube to expand until it conforms to the desired shape. Its Marzocchi Bomber 120mm fork provides plush travel up front and offers plenty of adjustment for dialing it in for your terrain and riding style. The tapered headtube sits at 68-degrees and lets you hang it out on the descents and still have the ability to pick just the right lines on uphill switchbacks. The stubby 17-inch chainstays let you slalom through the tight trees and makes getting the front wheel up and over trail furniture and wheelies a breeze. Built up in this configuration, this Air 9 features SRAM's SX Eagle 1x12 drivetrain giving you the same wide range as SRAM's higher tier offerings....

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
