2017 Niner AIR 9 RDO
The [R]evolution continues at Niner Bikes this year. Completely redesigned, this year’s AIR 9 RDO can stand tall with the best of them. And in the words of Niner. “Bigger is Still Better.” And this is the best 29er they have ever built.
At the heart of RDO is a process called the Carbon Compaction System. Niner describes it this way, “For a carbon structure to be as light, strong and durable as possible, the layers of carbon cloth need to be properly aligned with as few voids and extra resin as possible.” They achieve this by wrapping carbon around an EPS foam internal mandrel and then compact the entire system inside a mold. That way they can control wall thickness throughout the frame and force out any extra resin. What does this mean? Besides making the frame strong and durable, they shave 10% off the total frame weight.
This is first and foremost a racing bike. RDO stands for “Race Day Optimized.” So Niner altered the geometry to make it a more aggressive racing bike. They dropped the handlebars to put the rider in attack mode and they lengthened the cockpit as well as slackening the head angle. This gives the bike, “razor sharp handling when slashing single track at speed.” You can expect to see many Air 9 RDOs on the podium this year.
But Niner realized it had another audience for this bike as well. Not everyone is a racer, some people just want to own the lightest race worthy hardtail Niner offers for their weekend mountain adventures. Riding this bike in its aggressive position all day would be uncomfortable given how low the bars are. So to cater to those who don’t want to race, Niner made the bike compatible with a 120mm fork. That fork size will force the aggressive riding position up and back into more neutral territory by bringing the bars up and shortening the reach. Something that will dramatically increase comfort, making this bike perfect for all those all day mountain adventures.
Niner also shortened the chainstays, but not by too much. They wanted to make the bike feel light, but not twitchy. So they shortened them by 4mm to a targeted 435mm. This should make handling a lot more responsive, something you need in a big race.
Niner put a lot into its [R]Evolutionary Air 9 RDO. Whether you are a racer, or just want to own an RDO bike that is the best 29” hardtail Niner has ever built. This is your year.
