OUTLET: BIKE IS USED, WAS RETURNED. IN GREAT CONDITION AND READY TO RIDE

Niner Air 9 RDO 4 Star X01 Bike

The Niner Air 9 RDO is a full-on geared-only race machine. Niner has proven year after year that they have 29er hardtail geometory down, which they are demonstrating yet again with the new Air 9 RDO. The Air 9 RDO features fully-housed internal cable routing, new carbon layup, smaller junctions, tapered headtube, a newly positioned rear disc brake post mounts, and a PF30 carbon bottom bracket shell. Niner decided to go with a PF30 bottom bracket shell for the Air 9 RDO geared-only carbon hardtail to negate the need for an alloy insert which ultimately saves weight. The PF30 bottom bracket shell allows for 24mm or 30mm spindle cranks to be installed, however this frame is not compatible with an EBB (hence ‘geared-only’). Also, repositioning the rear brake mount inside the chainstay has helped make the whole rear end much stiffer. Niner is now using tapered headtubes on all their new frames creating a stiffer front end which drastically improves the handling. On the new Air 9 RDO, Niner also decided to go with a very sleek integrated headset that is lightweight and easy to install and maintain. Although it’s “Race Day Optimized”, the new Air 9 RDO is an awesome bike that anyone could enjoy. Providing their proven hardtail geometry on a lightweight carbon frame Niner definitely knew what they were doing when they designed the new Air 9 RDO.

X01 brings SRAM’s 11 speed mountain drivetrain to the masses with a lower price point without sacrificing performance. X01 is slightly heavier than XX1 (the difference is under 100g) but is still much lighter than any 2x10 setup out there while still offering a wide gear range thanks to the 10-42T X-Dome cassette. The new X01 cranks feature carbon arms and a removable spider (much like the X0 cranks) along with SRAM’s new X-Sync tooth profile which acts as a built in chain guide system. The rear derailleur’s X-Horizon design eliminates any vertical movement which reduces shift forces and prevents “ghost shifting”. The X01 drivetrain brings the latest and greatest SRAM technologies to your new complete bike offering a simple, clean, and more importantly, reliable drivetrain to your Niner Air 9 RDO.
