In addition to the Tamale Red SIR 9 shown at the new frame’s launch, the steel Niner will also be offered in Arctic White if the Blaze Yellow isn’t your thing. Using the same proprietary tubeset that was introduced with the bike, the SIR 9 uses a Reynold’s 853 DZB (double zone butting) front triangle to offer fork clearance and plenty of strength. A 44mm Reynolds 631 head tube offers plenty of fork options while the 142x12mm dropouts and Niner Biocentric II BB system allow for clean single speed or geared use.

sliders please.

They are out of touch with modern times. Should be 27.5 wheels.

Topmounter - 12/03/13 - 2:58pm

He’s just in denial.

29ers are so 2011.

I will never again purchase a bike with an EBB. Don’t know why some companies are so stuck to the EBB when adjustable dropouts are so much better.

142 is why! every thread is about 26,27.5,29er if it has 2 wheels go out and rip! My Niner rips, (Air 9 RDO) for all of MY riding needs!

I really like the yellow….must be the new white.

Can somebody explain this to a non-engineering person: “Shimano XTR double cranks have a non-standard chainline and are not recommended”? Why does SRAM and XT double work versus XTR?

@sillybike – I agree. still ride my garage full of 26′ers and very happy and don’t feel the need (yet) for a 29′er. Next purchase though.

Nice job niner!

I have adjustable sliders on my BUSS and an EBB on my Sir9. I prefer the EBB. They creak, unless you actually service them once in a blue moon…. proper grease and a torque wrench are your friends.
