When it comes to high-end mountain, cyclocross, and adventure bikes, Niner Bikes is an industry leader. Under the management of President and Co-founder Chris Sugai, the brand has managed to build an impressive range of bikes across multiple disciplines.
Currently, Niner’s main headquarters are in Fort Collins, Colorado. Their philosophy embodies passion and dedication to off-road riding, and they say they are ‘100% committed to impeccable designs and exquisite ride quality.’
Among their latest design features is the inclusion of 29” wheels in their mountain bike range, and a technological principle known as CVA suspension – which controls the unwanted movement of suspension components without the use of compression damping or manual lockouts. Their new carbon compact system features 9 of Niner’s models which emphasize making use of rigid internal structures.
Niner bikes is a brand that uses consumer feedback as a way to improve and as such, they often use their sponsorship program to gauge responses to new bikes and technologies.
As a member of the International Mountain Bike Association (IMBA), they also support the development of great trails across the U.S. to therefore grow the mountain bike community without the need for riders to travel long distances to find a suitable place to shred.
Niner is a relatively new company, after being founded in 2005 by Chris Sugai and Steve Domahidy. This American bicycle manufacturer has its headquarters in Fort Collins, Colorado where it specializes in 29er bikes (two-niners), mountain bikes that are built to use 29″ wheels.
Niner Gravel Bikes Review
The popularity of 29ers in the late 2000s helped the company’s growth in the sector. By 2011, the Niner Bike company was recognized by Forbes “as one of the most promising American companies in the world.”
Currently, Niner Bikes is owned by the UWHK Ltd. group, a Hong-Kong-based investment firm after they acquired the brand in 2018.
Niner Bikes History
The pioneers of 29″ wheels
Niner bikes were founded in 2005 by Chris Sugai.
While running a successful car tinting business, he played around with the idea of 29″ wheel bikes. He was riding his own 29er single-speed bike at the time and noticed how much faster he was than the other local riders – not due to fitness, but due to the bike’s build. As a businessman, he recognized a gap in the market and set out to build a new company, based around custom 29er bikes.
Eventually, as Niner Bikes took off, he sold his window-tinting business and focused full-time on bikes. He’s been the serving Chief Executive Officer (CEO) since then.
Niner believes in the benefits of 29ers and uses its platform to make them accessible to the wider mountain biking community, and took advantage of the rising popularity of 29ers in the late 2000s. Even though the design of the bikes takes place in its headquarters in California, manufacturing is done in Asian countries.
In a Forbes report in 2011, Niner was featured in the list of the most promising companies.
With over 300 global dealers, Niner Bikes has managed to increase its outreach to over 40 countries, coming a long way from its humble beginnings as a single person operation in 2005.
Constantly Varying Arc, or CVA™, is what Niner bikes rely on for suspension. Patented by the company, it’s unique to Niner suspension mountain bikes and boasts of a short dual-link, four-bar system. It’s ideal for the larger wheel and tire sizes found on modern bikes, including 29er, 27.5+, and wider 27.5″ tires (2.5-2.6).
The Magic Carpet Ride is a full-suspension set-up on a gravel bike. It is the world’s first drop-bar full-suspension gravel bike and uses Niner’s patented CVA suspension system.

The Air 9 manages to blend the efficiency and agility of an XC bike with the toughness of a trail rig. The frame is composed of hydroformed aluminum giving it plenty of stiffness while bringing down its overall weight.
The Niner bikes designers created the bike with a balanced ride in mind, making the Air 9 comfortable enough for all-day riding while remaining snappy and agile enough for those shorter days at the trailhead.
There are two component options available, the 3-Star Shimano SLX Singlespeed build which has an MSRP of $2,090, and the 2-Star SRAM SX Eagle, which has an MSRP of $1,800. Both come equipped with Marzocchi Bomber Z2 Rail forks and a Metallic Silver/Blue colourway.

This removes the requirements for extra gussets or tube reinforcements, creating a lightweight yet sturdy bike.
It’s available in several models, with the lowest MSRP starting at $2,550 for the 2-Star SRAM SX Eagle and rising to $6,290 for the 5-Star SRAM X01 EAGLE. It’s available in one colorway option; Cement Grey/Black.

Full Review: Niner AIR 9 & AIR 9 RDO
Niner RIP 9 RDO 27.5
The RIP 9 RDO 27.5 is one of Niner’s only 27.5 wheel sized bikes.
It is a 27.5″ wheel version of their flagship do-it-all trail bike. The RDO 27.5 offers a number of features, a CVA suspension system that’s supple yet stable and adjustable to each rider’s preferences; a lightweight carbon fiber composite that’s both strong and stiff, full sleeve cable guides for easy installation, and lightweight and nimble 27.5″ wheels.
But why manufacture a 27.5″ option? After a decade-long love affair with 29ers the brand decided to create a 27.5″ that has more standover, less rotating weight and handles faster and quicker than its bigger wheeled brother.
Available in four different setups, the MSRP begins at $4,400 USD for the 2-Star SRAM SX Eagle option, and increases to $8,000 USD for the 5-Star SRAM X01 Eagle set up. The bikes are available in a choice of two colourways, Satin Carbon, or Santa Fe Sand.
Niner JET 29 RDO
The Niner JET 29 RDO is a carbon trail bike featuring 130mm of front travel and 120mm of rear travel, built using Niner’s patented CVA suspension.
The bike is built to accept both 29er and 27.5+ wheels and is promised to be confident on the descents while lightweight and stable enough to tackle climbs comfortably. The addition of the CVA powered suspension makes the bike adjustable for each rider’s personal preference of ride feel.
The frame is constructed using RDO carbon fiber, which results in reduced resin pooling and excess carbon on the inside of the frame. This waste-reducing process allows Niner to create more intricate structured carbon frames and increases the strength of the bike without increasing the weight.
The MSRP starts at $4,100 USD for the 2-Star SRAM SX Eagle version, and increases to $9,550 USD for the 5-Star SRAM X01 AXS LTD version. The bike can be bought in either a Teal/Slate or Licorice colorway.

Just as at home on a black diamond trail as it is doing laps of the local bike park, Niner’s RIP 9 RDO 29″ is their reimagined flagship trail bike. Featuring their patented CVA suspension, the carbon fiber frame has increased stiffness and more progressive geometry than its predecessor.
This new version has enough room for 170mm dropper posts, a longer reach and a shorter head tube. All these things make it longer, slacker and more capable over the rough stuff. No matter the obstacle, with 29er wheels, this bike can handle it.
Available in several versions, the MSRP starts at $4,400 USD for the 2-Star SRAM SX Eagle model, and increases to $10,050 USD for the 5-Star SRAM X01 AXS/FOX X2 LTD version. It’s also available in three colorways; Baja Blue/Silver, Santa Fe Sand, and Satin Carbon.

It’s available in several builds, with the MSRP starting at $3,800 USD for the 2-Star SRAM SX Eagle build and rising to $9,050 USD for the 5-Star SRAM X01 AXS LTD version. There are two colorway choices for this bike, Satin Carbon Black/Magnetic Grey, and Grey/Orange.
