Product Details

2015 Niner SIR 9 2-Star SS

When Niner's SIR 9 tells you it's time to buck up and shred, you say, "Yes, sir!" 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.
