Niner SIR 9 returns as a trail/bikepacking mash-up

The hardtail renaissance continues with Niner’s all new SIR 9. Niner bills it as a “do it most” bike, and that sums it up pretty well if you ask me. And if you are reading this, it is easy to assume you are asking me.

Some highlights from Niner:

  • Reynolds 853 steel provides the supple, comfortable ride this legendary material is known for
  • Compatible with 29×2.5 OR 27.5×3.0 to offer the choice of maximum rollover or ultra traction and stability
  • Revised geometry is optimized for modern trail riding, long days in the saddle and all-around good times
  • Integrated bag mounts inside front triangle
  • Bento Box mounts on top tube offer additional storage options within reach
  • 73 mm PF 30 BB shell is geared or singlespeed compatible with the Niner Biocentric 30
  • 148 x 12 Boost rear spacing
  • Compatible with 1x (max ring 36T) and 2x (26/36 or bigger) drivetrain systems
  • Compatible with 2x (26/36 or bigger) drivetrain systems, 34.9 sideswing front pull derailleur

The SIR 9 sweats the small details and looks more like a one-off custom rig than the average production hardtail.

Set up for tripping or ripping, this bike fills a surprisingly empty niche between steel bikes like the Surly Karate Monkey and custom.

Complete bikes start at $3,000 and top out at $6,000 which gets you Eagle XO1 and carbon wheels. Those looking to for a custom build can pick up a frame for $1,200.
