Product Description
SIR 9 27.5+ 2-Star Complete Bike by Niner
There's a very good reason why many custom frame builders use steel to this day. Premium steel alloys, like Reynolds 853, are revered for their strength and ability to add a springy, lively ride. When you put that material in the hands of the mountain bike maestros at Niner, you can bet you'll get modern trail geometry, the ability to run 27. 5+ or 29-inch wheels, and a bevy of mounting points for bikepacking adventures. So if you're looking to get back to your steel hardtail roots or a new riding buddy for all-day and overnight adventures, the SIR 9 27. 5+ 2-Star Complete Bike gets you simplicity, strength, and unmatched versatility. We love the ability to run the voluminous plus tires in this configuration for flotation and grip over loose and chunky terrain and with a simple wheel swap, you can change the ride to momentum-carrying 29er wheels for maximum roll over and mile munching. As mountain bikes continue to evolve, Niner took it upon itself to modernize the SIR 9's geometry into something a little bit more trail-oriented. Niner's [R]evolutionary trail geometry makes the SIR 9's reach a bit longer while shortening the chainstays for snappy handling on tight trails and more stability with its roomier cockpit, giving it more composure up and down the trail and at high and low speeds. The slightly longer wheelbase inspires confidence on steep, rough downhill portions of the trail allowing you to ride terrain typically reserved for full suspension bikes. Up front, a RockShox Judy Gold RL Solo Air fork with 120-millimeters of travel gobbles up the terrain and kicks the head tube angle to a very trail-worthy 68-degrees. This provides the chops to attack fast descents and technical sections with more confidence than typical XC hardtails. That slackness up front doesn't sacrifice its pedaling and climbing ability though, as Niner designs it with a steep 74-degree seat tube angle, which places you in an optimal pedaling position.

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.
