Overview
About this bike
Niner's SIR 9 stands at the front of the class ready to teach you a lesson in shred. The learning starts with Reynolds 853 DZB steel for the legendary ride of steel coupled with the ability to create custom bends in the down tube for amazing strength. With a RockShox Reba fork up front, trail chatter is quieted handily with 100mm of travel. Get-up-and-go pedaling transfers directly into forward power when you stomp on Shimano's XT drivetrain; it's ready to burst you forward, glide you up climbs, and accelerate on the descents. Stan's ZTR Arch EX wheels slay tech and roll over everything else, while Shimano XT disc brakes slow it all down in a pinch. Top it off with a host of Niner components including a light carbon bar and seatpost for speedy ride that brings you to the head of the class on the quick.
