Overview
About this bike
When Niner's SIR 9 tells you it's time to buck up and shred, you say, to;Yes, sir!to; The fun 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 carbon fork up front, trail chatter gets quieted handily and your get-up-and-go pedaling transfers directly into forward power. Stan's Rapid wheels slay tricky climbs and float down your favorite descents, while Shimano Deore hydraulic disc brakes slow it all down in a pinch. Top it off with a host of Niner components including a Cogalicious rear cog and a light aluminum seatpost for a one-speed trail ripper with some serious heart and soul.
