Niner One 9 Frame

Niner One 9 Frame

A 29" single speed. What else do you need? Niner set out to create the ultimate 29'er singlespeed frame, built around hydroformed aluminum alloy tubing and their superlight eccentric bottom bracket (EBB). With an EBB, you can use a common, readily available quick release rear wheel - no need for a special nut/bolt on hub. That means easy wheel installation in the event of a flat, and perfect, repeatable chain tension every time. This is the lightest production 29'er singlespeed frame on the market. Blazing fast, no flex, without a harsh ride, thanks to Easton's tubing expertise. Fast, nimble, and comfortable.

  • The One 9 is easily converted between geared and singlespeed modes.
  • The CYA bottom bracket system works with all bottom bracket options currently available.
  • Removable cable guides means no clutter while in singlespeed mode.
  • Replaceable derailleur hanger comes with Niner's bottle opener dropout for singlespeed mode.
  • 31.6mm seatpost diameter, 400mm recommended length, 34.9mm clamp.
  • Comes with Niner Bio-Centric™ bottom bracket, 73mm standard threaded, inserts for other standards also available separately.
  • 51mm IS disc brake mount (no rim brakes)
  • Geometry designed for 80-100mm fork

Niner's the ONE
I ride it in the mountains and rice plantations of southeast Asia. Rain, super steep roads, dust . . .

It's confidence inspiring on a 50MPH paved downhill and fun on dusty or muddy singletrack.

Silly light with great ride quality - not unlike my old Ti HT (Merlin).

PROS: Niner Quality Geometry, Niner Quality, Lightweight, Attractive Design, Geometry, Durable

BEST USES: Mountain Biking, Racing, Upgrade

I am now a Niner guy!
I am 6'2" (32' inseam) and I tried a 2009 L, and it was too small. I have been riding a 2009 21" SE Stout, so I ordered the One 9 XL. The fit is great, and the 6 pounds of weight that was dropped is even better! I installed the EBB as per the Niner manual with pipe compound, and so far so good... no slippage as lot of forums have talked about. Time for another ride!

PROS: Great Craftmanship, Eccentric Bottom Bracket, Looks great, Scandium Frame

CONS: I Didn~'~~t Buy One Sooner

BEST USES: XC, Passing Geared Bikes
