The 4-Star version of the Niner RIP 9 RDO comes with a Shimano XT M8100 drivetrain. This includes a cassette that has a hill-crushing 10-51T gear range that makes climbing and pedaling through rough terrain much easier.

Made for trails

The advantage of this mountain bike is that it’s specifically intended for diverse terrain. With it being an All-Mountain/trail bike, you can navigate your way through mountainous paths without too much hassle. Couple that with a light, yet durable, carbon frame, and you can undoubtedly rely on this bike irrespective of the trail’s difficulty.

Styling options & brakes

Not only that, when it comes to style preference, it’s available in 2 different color options – a dark satin carbon and a silver/ baja blue. Additionally, the hydraulic disc brakes provide you with unmatched control. You can stop the bike at a short distance. With features like that, it’s difficult to ignore this mountain trail bike in favor of any other. However, these are not the only features of this bike.

Efficient suspension system

The Constantly Varying Arc (CVA) suspension system ensures that you get proper stability. Not only that, you can control the bike easily while climbing as well as while descending. Even when covering mountainous trails, you won’t have to worry about bumps or jerks. The suspension system certainly makes it stand out.


Carbon frame

Without taking a look at the frame of the mountain bike, choosing one is a mistake. Fortunately, this one consists of a carbon frame. The carbon frame has two advantages. The first advantage is that it’s pretty lightweight. Due to this feature, controlling the bike is effortless. Another advantage of a carbon frame is that it can handle any weather and has a durable design. As a result, it becomes easy for you to use this bike for years to come.

Hydraulic disc brakes

As we stated above, the bike consists of hydraulic disc brakes. The disc brakes have excellent stopping power. The hydraulic design means that they are incredibly reliable. The amount of maintenance which they will need is also minimum due to the same.

Easy to adjust the saddle

Not everybody needs the saddle at the same height. With the help of a lever, you can easily adjust it up or down. You will not have to spend a lot of time on finding the perfect position. Also, the lever requires minimal effort to adjust the saddle. That adds to the convenience.

Reliable tires

When you’re covering trails, you will be navigating rugged terrain. The tubeless tires ensure that you can do so without any worry of punctures or deformities of the tires. Thus, with every feature taken care of, you cannot go wrong with this NINER RIP 9 RDO 29 4-STAR BIKE 2021.

RIP 9 RDO 29 – Niner Bikes

The trail taming RIP 9 RDO For more than a decade, the RIP 9 RDO trail bike has ruled our off-road lineup. For 2019, this flagship bike evolves again. Our do-it-all trail bike hits the sweet spot with 140mm of consistent, controlled CVA suspension, progressive and adjustable geometry, and increased frame stiffness.

The evolution is the Niner RIP 9 RDO 29 4-Star Bike. It starts with an RDO carbon frame that has 140mm of travel on the rear and 150mm of travel on the front. The CVA suspension is built to be supple yet stable, controlling unwanted suspension movement with calibrated anti-squat, yet remaining active while climbing and descending.

The seat tube angle is a conservative 75.2 degrees in the low mode, which matches the bike’s intended purpose nicely. The RIP 9 RDO will feel best while climbing standard grades from about 6 to 10 percent, and the 434-millimeter chainstay length helps to keep the front wheel on the ground for most climbs.
