With a whopping 18 mounting points for everything from bottle cages to bags to racks and more, the new Niner SIR9 hardtail is back and better than ever. As one of their original models, Niner’s been getting a lot of questions about when it’d make a return. But they took their time because things were changing. The way we use our bikes is changing. So they wanted it to be able to handle anything you might want to do. Compared to the original, it retains the Reynolds 853 heat treated, air hardened, butted tubing, but the details are all new…
Like the new JET9 and RIP9, the new SIR9 has Boost axle spacing and is designed to run 29er or 27.5+ mountain bike wheels and tires. Geometry is designed around a 120mm fork, and with a modern tapered headtube, you could run any model you want.
Rack, fender, bag and Bento box mounts are all over the bike, so you can add anything you want. All cable routing is external, with a dropper post cable port on the seat tube to bring that one inside for stealth models.
The chainstay yoke was formed in top- and bottom halves, then welded together sandwiching another steel plate to improve rigidity. This design let them keep the overall shape as thin as possible without compromising tire clearance or the ability to fit a double (or even triple) chainring. The pressfit BB offers options, including their own eccentric BB for singlespeed builds.
They also offer geared and non-geared rear axle inserts, keeping singlespeed builds super clean.
At the top of the range is the 5-Star build with SRAM X01 Eagle for $6,000 built with Niner’s carbon XC wheels in 29er. Shown below that, it’s also available with Stan’t NoTubes Neo ZTR Arch wheels in 29er and 27.5+ for $5,000. Complete bikes start at $3,000 with an SLX 2-Star build. It’s also available as a frameset for $1,200.(UPDATE: That green/black colorbwe had posted originally was a sample color only, not a production option). They start shipping now.
