Overview
About this bike
Think steel is a thing of the past? Niner's S.I.R. 9 begs to differ: it has all the modern amenities to make it a stealthy singletrack slayer. It all starts with Reynolds 853 DZB steel that gives you the comfortable ride of steel coupled with the ability to create custom bends in the downtube for amazing strength. With a RockShox SID XX up front, trail chatter and big bumps get quieted handily. Stan's NoTubes ZTR Arch EX wheels slay tricky climbs and float down your favorite descents, while SRAM Elixir 9 Trail brakes slow it all down in a pinch. Get in the right gear for those quick ups and get all the push you need on the descents with SRAM's X01 11-speed drivetrain. Top it off with a host of Niner components, including a carbon seatpost for an ageless trail ripper with a modern heart and soul.
