If the previous colors offered for Niner’s frames were a little too tame for you, get ready to stand out in the woods with the new Blaze Yellow color way. Offering up two new models that would fit right in to our Hi Viz Interbike roundup, Niner’s Blaze Yellow SIR 9 and One 9 RDO are the newest options in their line up. Add in 1x and single speed capabilities with Niner’s renowned ride and you have the makings for some really bright bikes.
Check out the Trailblazers after the jump.
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.
