Niner SIR 9 2-Star NX Eagle
This variant is currently sold out
Take charge of your ride with this Reynolds 853 Steel frame designed around Niner's [R]evolution trail geometry which begs the rider to push their limits.
Ride it hard. Ride it fast. After all, it's made from a truly time-tested material that's been air hardened and heat treated. The efficient, yet compliant ride quality of the SIR 9 harkens back to a simpler time. A time without linkages and complicated shock settings. A time where all the energy you put into the pedals moves you forward.
- Redesigned bottom bracket and chainstay junction: Keeping ride quality in mind as well as tire clearance, we went to great lengths to design this crucial frame junction. The PF 30 Bottom Bracket allows you to run a standard press fit bottom bracket or, if simplicity is your thing, throw in an eccentric bottom bracket and run single speed. A hidden plate inside the chainstay yoke stiffens and strengthens in order to improve power transfer.
- Multiple mounting options: Pack it in, pack it out: Eighteen. As in 18 mounting points allow you to run racks and fenders, a bento box, water bottles, etc. This frame is versatile.
- Niner's [R]evolution trail geometry: Our trail geo puts the rider in the sweet, balanced spot on the bike.
