RIP RDO 29 4-Star Complete Mountain Bike

Since its introduction over a decade ago, Niner's RIP 9 completely changed the landscape of all mountain riding and eliminated any preconceived notions of how big travel bikes with big wheels were supposed to ride. Fast forward to today and this all-new 3rd generation frame is here and ready to rock the trails with plenty of new features like Rib Cage construction for added stiffness, extra standover height and room for longer dropper posts, a high/low flip chip adjustable geometry, and 140mm of re-tuned CVA suspension. Add some FOX Factory suspension and SRAM's X01 group with updated, progressive geometry for modern trail bike handling and you get the RIP RDO 29 4-Star Complete Mountain Bike, a machine that will help you redefine your limits on any trail.

One thing to note right away with the new RIP is there are two frames dedicated to each wheel size: 27.5 and 29-inch. This allows Niner to optimize the frame for each wheel size by dialing in the suspension kinematics and geometry specifically for each size with no compromises. Either way, you're getting 140mm of CVA rear travel that’s sensitive off the top and supportive in the mid-stroke paired with 150mm of fork travel and clearance for 2.6-inch tires with room for mud. This is the longest, lowest, and slackest Niner ever created, however, with the inclusion of its adjustable geometry via flip chips at the seatstay pivots, a Niner first, you can make adjustments as needed for your terrain and riding style.

The high mode geometry is perfect for tamer trails and daily riding. You'll quickly appreciate the climbing and pedaling efficiency of its steeper 75.8-degree seat tube angle and reworked CVA suspension platform. On the way down, you can shred with confidence given its longer reach, slack 66-degree head tube angle, and 44mm reduced offset fork. If you have some shuttling or bike park laps on the docket, its low mode brings out even more aggression by slacking out the head angle by a full degree (65-degree) and lowering the bottom bracket by 7mm. Niner further gives its sendy blessings by shortening the seat tube by 20mm to accommodate longer, 170mm dropper posts as well as increasing the standover height, a boon for shorter riders. Furthermore, a lower stack height and a shorter head tube accommodates a wider range of fit and varying rises of handlebars. Lastly, the short, 435mm chainstays on this 29er version ensures the bike can handle tight singletrack trails as well.

Visually, one feature that's immediately apparent in the new frame design is its wide and stiff Rib Cage struts on the main triangle. This, in conjunction with the flattened top and down tubes, a wider main rocker link pivot, and an oversized rear triangle boosts the frame's responsiveness for precise handling. Things that might not be so noticeable are the durable and long-lasting Enduro MAX Black Oxide bearings at the pivots and Niner's wonderful end-to-end, full sleeve internal cable guides making any maintenance down the road a breeze. Other frame niceties include a sag indicator on the rocker link pivot, factory installed scuff guards and frame protection at vulnerable locations, FOX Live-valve ready, water bottle compatibility inside the frame, and a creak-free threaded bottom bracket with ISCG 05 chain guide mounts.

On the trail, you'll notice the struts reduce bottom bracket deflection down below for efficient pedaling while allowing the upper portion of the front triangle to remain compliant and better able to track across rough rock gardens, while the wide, flat surfaces found on the top and downtube help to absorb frontal impacts and vibrations from repeated waterbar pounding while resisting deflection under a torsional load. And since the rear triangle receives beefier tubing, it allows Niner to remove the seatstay bridge at the rocker link opening up extra room for wider rim and tire combinations.

As we mentioned above, the RIP receives an updated CVA platform that's designed to increase pedaling efficiency by riding more in the mid-stroke of the travel. We experienced gobs of traction when scaling technical climbs while remaining sensitive and fully active, even under braking, while descending. It basically takes Niner’s proven patented CVA linkage layout and axle path and refines the leverage ratio curve for supple travel early in the stroke, more support in the mid-stroke, and progressively ramping up at end stroke.

The new, higher leverage ratio off the top makes it easier to set the shock in motion and overcome static friction. At the mid-stroke, the leverage ratio decreases toward the sag point so less rear wheel force is transmitted to the shock. This allows the shock the ability to hold the rider up in the travel, giving solid mid-stroke support. And at the end stroke, the leverage ratio increases just slightly to overcome the natural progressivity of an air spring for bottomless, smooth response under the biggest hits.

A two-wheeled Monster Truck

  • Familiarity: I've used it once or twice and have initial impressions

First of all, this bike is really fun. I was blown away by how well it just ate up everything in front of it, no matter how lazy I was with my line choice. That being said, for those times when you needed to pull some more intricate moves, it was still quite responsive. When it comes to pedaling, I felt that it maintained good efficiency. It was by no means a XC bike, but I think that most people would be very happy with how it handled climbing, whether that be long sustained sections or more technical steep climbs. I found the geo was slack enough to put you in a comfortable position for descending confidently, but not too awkward for sitting in the saddle and climbing. In terms of the build, I thought everything was a perfect fit, other than the saddle. I am not a fan of these stock Niner saddles, but most people have a go-to saddle anyways, so it's not a huge issue for most. Overall, it is an absolutely killer bike if you want a bike that you can take down even the most rough and loose trails!

Niner might not be the most popular and sought after bike on the market BUT this bike impressed me!

From green flowing trails to double black chunk gnar, this bike handles it all.
The Geometry is not as slack as I am used so it took me a few laps before I felt comfortable, especially when it came to steeper descents. The Rip 9 handled jump trails really well and I felt extremely comfortable in the air and on small drops. Again, I believe the geometry was a factor for me on technical trails as I felt like I might fly OTB when it got steep.

All in all, this bike pedaled really well, cornered easily and made me smile on Jumps. This would be a great choice for someone looking for a versatile bike that handles almost anything with ease.

When I rode the previous generation RIP 9, I was confused. With the mid-long travel category becoming so popular in the last couple of years, it seemed like a slam dunk for a company named NINER to jump in on this. However, the previous generation was still lacking quite a bit compared to groundbreaking bikes like the Ibis Ripmo. It turns out that the wait was worth it and Niner has finally delivered the bike that everyone wanted to see. This ticks all of the boxes when it comes to cliche bike terms. It's longer, lower, slacker, floats up the climbs, smashes the descents. It's hard to find something that this bike can't do. With a 150 up front and 140 in the rear, this bike settles right into the all mountain category and could comfortably be your only bike. The term "quiver killer" comes to mind. Niner also knocked it out of the park on the component spec. All versions come with a Fox 36 and SDG Tellis dropper post which i'm a fan of. If you have any preconceived notions about Niner as a brand, I would recommend you let this bike change your mind.
