Niner Air 9 RDO Mountain Bike Frame - 2016 Black/Chrome, XL

If you glance at the specs, you'll notice that the 2016 Niner Air 9 RDO Mountain Bike Frame is roughly 100 grams lighter than the previous version. This was accomplished using Niner's Carbon Compaction System (CCS) . This process allows the Niner engineers to create tubing that is near perfect in shape and wall thickness, without wasted carbon or resin build-up. Without the cushiness of a rear shock, Niner went to town to design a frame that not only dampens vibration and minimizes chatter, but also moves impact forces to the larger and stronger areas of the frame so you can take a hit from rougher trails. The bottom bracket is designed for a PF30 and your pedal power is transferred to the rear drivetrain via the same chainstays as the previous version. The difference is that Niner has added a 12x142 Maxle to the rear dropouts. The oversized downtube keeps the bike holding tight to the line you choose, and its clearance

allows for tires up to 2. 4in wide.
