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.
