Niner SIR 9 XTR JensonUSA Exclusive Build

There’s never been a better time to get away and now you can with the bikepacking bike of your dreams. The Niner SIR 9 XTR JensonUSA Exclusive Build is a versatile, trail-rated, fully-loaded steel hardtail that is ready to take you on your next adventure. The Niner SIR 9 is built around a hand-welded Reynolds 853 steel frame for superior durability. 18 mounting points peppered throughout the bike allow you to mount all the storage bags, racks and water bottles you could ever need. The Niner SIR 9 was designed to be able to tackle any terrain and features trail-specific geometry. With a 68-degree head tube angle, a 74-degree seat tube angle, short chainstays and a long top tube and wheelbase, the SIR 9 offers stability when you’re dropping into the steepest lines and maneuverability in the technical stuff. With clearance to run 27.5” plus tires or 29” tires, you have the freedom to convert your SIR 9 into a fast rolling 29er or a beefy 27.5+ trail ripper.

Th XTR JensonUSA Exclusive Build of the Niner SIR 9 bike comes expertly spec’d with Shimano’s XTR drivetrain and brakes and Fox’s new 2021 Float Factory Step-Cast Fork. The Shimano XTR CS-M9100 cassette features a hill-crushing, 10-51 tooth gear range to get you up any hill. When you have to slow down fast, you can rely on the Shimano’s XTR BR-M9120 Disc Brakes for excellent stopping power and modulation. Fox’s 2021 Float Factory Step-Cast 34 Remote Fork soaks up the bumps in the trail and provides a smooth ride. The Niner SIR 9 XTR JensonUSA Exclusive Build is a must have for riders looking to experience a hardtail like they never have before.
