Niner Bikes Review

When it comes to high-end cyclocross and adventure bikes, Niner Bikes Company has the entire package. Under the leadership of Chris Sugai, it has managed to build mountain bikes and touring bikes. Currently, its main headquarter is based in Fort Collins, Colorado. Niner’s philosophy is to be more passionate about what it does, and according to them, that is the best marketing policy. The latest design features 29” wheels; it uses a technological principle known as CVA.

Niner is always excited when ardent clients give good feedback. On the other hand, the company believes that negative feedbacks give room for improvement. Through several sponsorship programs, it has managed to join other single-track cyclers to enjoy the exciting experience. As a member of the International Mountain Bike Association (IMBA), it has taken part in organizing for high-end bikes and accessories.

The new carbon compact system features 9 of Niner’s models which emphasize making use of rigid internal structures.

Niner is a relatively new company. It was founded in 2005 by Chris Sugai and Steve Domahidy. This American bicycle manufacturer has its headquarters in Fort Collins, Colorado. The company specializes in what is known in the field as 29es (two-niners ); mountain bikes and hybrid bikes that are built to use 700c or 622 mm ISO wheels, commonly called 29″ wheels.

The popularity of 29ers in the late 2000s really 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 Bike is owned by the UWHK Ltd. group, a Hong-Kong-based investment firm. The company is also one of the main supporters of the International Mountain Bike Association (IMBA).

The management of the company believes in open communication with its employees and partners as a way of generating better ideas. Niner’s slogan, “pedal damn it” is the inspiration that drives them to create better wheels and more efficient pedals in a quest to satisfy the riders’ needs.



Back in 2005, Niner was formed by Chris Sugai. He founded the company after quitting his window-tinting business to pursue his biking dreams. Since then, he has been serving the company in the capacity of a Chief Executive Officer (CEO).

Niner believes in 29ers for the mountain biking community. It took advantage of the fact that 29ers were becoming popular in the mountain biking domain, especially in the late 21st century. Even though designing takes place in its headquarters in California, manufacturing is done in Asian countries.

According to a Forbes report in 2011, Niner was featured in the list of the most promising companies.

True to the fact, it has worked in its production and marketing strategies to fulfill this prophecy that hints at greatness. With more than 300 dealers, it has managed to secure market entry into 40 countries. The new RIP 9 RDO has facilitated Niner’s partnership with Push industries to generate improved shock systems for bike suspension parts.


Technologies Used

bikes rely on constant varying Arc (CVA).  The bike company has been awarded patented rights thanks to its unique mountain bike suspension model. CVA boasts of new and improved 29 inches for wheels against its competitors. With super-efficient paddles, the rider’s ability to ride on the harshest trails has been made easy.

The Magic Carpet Ride is a full-suspension set-up on a gravel bike. Matter of fact – it is the world’s first drop-bar full-suspension gravel bike using the CVA suspension system.

Niner – Air 9

The Air 9 is one of Niner’s most durable, affordable bikes. It is an aluminum hardtail with the spirit and mechanics of a trail bike.

The Air 9 manages to blend the efficiency and agility of an XC bike pedaling system 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.

Engineers at Niner applied advanced geometry to its makeup, allowing the driver to uncover a balanced ride every time. The Air 9 is comfortable enough for all-day travel and cycling. Spec-wise it features a 3-Star Shimano SLX Singlespeed build kit with a MARZOCCHI BOMBER Z2 RAIL fork. Overall it is a capable, versatile hardtail that works both off-road as well as on the road.

Niner RKT 9 RDO

The RKT 9 RD is a carbon full suspension XC race bike. All bikes in Niner’s RKT line are great, but the RDO ups the ante and includes more versatility with a sturdy 120mm suspension fork and a tweaked geometry. The RDO has 90mm of efficient CVA rear suspension as well as Niner’s legendary lightweight frame composite.

One of its biggest highlights is Niner’s Constantly Varying Arc, or CVA, suspension design. It is a patented short dual-link, four-bar system, developed in-house and constantly being upgraded. The system is built to velvety yet stable, easy to control, and with calibrated anti-squat features.

The RDO also has some of the most stout pivots and bearings in the market, lightweight but enough to weather all storms.

Each bike is trail tuned and adaptable to the rider, offering a stiff rig, that’s durable, versatile, and easy to set up and customize.

Review: Niner AIR 9 & AIR 9 RDO

RIP 9 RDO 27.5

The RIP 9 RDO 27.5 is one of Niner’s only 27.5 wheel size monster. It is a travel size, do-it-all trail bike that has become the company’s flagship over time. the RDO 27.5 offers amongst its great features, a CVA suspension system that’s supple yet stable and willing to take any brunt; a lightweight carbon fiber composite that’s both strong and stiff, full sleeve cable guides for easy installation, and maintenance of the bike’s mechanics.

But why the comprise? Why switch from 29 to 27.5? Niner heard its audience and after a decade of love affair with 29ers decided to create a great 27.5 that has more standover, less rotating weight and handles faster and quicker. They applied every concept in their back of tricks to maintain the spirit of a 29 inside the frame of a 27.5. The name? Simple Rest In Peace 9 (RIP 9).

Niner bikes can be bought from their online shop or from JensonUSA.com. Before getting it ready for shipping, Niner’s experienced technicians ensure that the braking and shifting are taken care of. Also, the headset and bottom bracket are aligned in a proper manner. The handlebars, seats, and wheels are separated to facilitate easier packing. Upon receiving your new bike, you will simply need to cut through the zip ties and reassemble it using a torque wrench and a pair of scissors.

You will find a plastic folder that indicated the quality control checklist. Cross-check if the serial numbers match. You can also check out their Setup Instructions for more info. Remember, doing it yourself is cheaper but it’s not advisable if you don’t know what you’re doing.

If all these details seem like gibberish to you, look for an experienced mechanic at a nearby bike shop to do your assembly for you at a small fee. If you want to avoid all the above scenarios that involve a lot of thinking, then you should simply order a complete Niner bike from Amazon.
