Big-wheel evangelist Niner may have a reputation for its frames, but with the RIP 9 4-Star X01 Complete Mountain Bike, Niner proves that it's just as serious about its complete offerings. This aluminum framed trail bike features an assortment of RockShox and FOX's finest suspension that's been rounded off with Stan's NoTubes wheels and SRAM's new X01 eleven-speed drivetrain. All you have to do is ride it. And trust us, you want to.

At the heart of this bike is the widely popular RIP 9 frame. And it's not popular by accident -- the list of features reads like a wish list for trail riders the world over. Starting with Niner's patented Constantly Varying Arc (or CVA) suspension platform, you get 125mm of travel. And the feel is decidedly different than many other five-inch travel trail bikes. It's a suspension system that's optimized specifically for 29-inch wheels, so you're not dealing with a bike that was designed for smaller wheels and adapted to fit bigger hoops. The result is that Niner takes advantage of the improved rollover characteristics of larger wheels, and in turn, tunes its suspension to have a firm, efficient feel. Niner placed extra stiff links in positions that isolate pedaling forces, while remaining fully-active under all conditions. Notice that the lower-link sits below the bottom bracket. This places the CVA's instant center in a virtual position located ahead of the drivetrain, causing chain tension at the rear axle to pull the two linkages in opposite directions to effectively isolate the drivetrain from the rear triangle. This means that when you stomp on the pedals, no energy is wasted, but you still have plenty of travel in reserve for when you miss your line.

It's around half-a-pound heavier the carbon fiber RIP 9 RDO frame, so the alloy RIP 9 is no heavyweight. But, despite its light overall weight, the air-formed tubing and oversized hardware mean that this is a bike that's ready to be ridden hard, day-in and day-out. The 142x12mm dropouts boost stiffness, and the Maxle rear axle ensures that wheel changes are as fast as ever. You'll find a 30.09mm seatpost, which means that you have options should you upgrade to a dropper post. And whether you prefer a front derailleur or a one-by drivetrain, the S3 low-direct derailleur mount and ISCG05 chain guide mount leave the choice up to you. And for the headset, the ZS44 top cup and ZS56 bottom cup ensure compatibility with the latest generation of tapered forks.

A bike this trail-worthy deserves a build kit to match. And with the new SRAM X01 drivetrain, that's not a concern. Building off of the venerable XX1 eleven-speed drivetrain, X01 features the same 42/10t XD cassette for a massive gear range with a single chainring up front. You'll enjoy flawless shifts and chain retention with the clutch derailleur and alternating narrow-wide tooth profile on the chainring. Stopping duties are handled by SRAM's four piston Elixir 9 Trail brakes, which deliver tons of power with a surprising level of control. The RockShox Monarch RT3 rear shock is well matched by the stiff and adjustable FOX 34 TALAS CTD fork. This fork's travel adjust feature makes it easy to lower your front end for precise climbing, then extend back to full travel when you're heading back down. The wheels are Stan's NoTubes Flow EX's, which pair well with today's larger sized tires, while also having the added benefit of being a breeze to setup tubeless. Lastly, the cockpit is rounded out with Niner's excellent handlebar, stem, and seatpost. In case it wasn't already clear, you won't need to upgrade. Like the name implies, this rig is ready to 'rip,' straight out of the box.

The Niner RIP 9 4 Star Complete Mountain Bike is available in four sizes from Small to X-Large and in the color Niner Green.

Medium Price, High Performance

  • Gender:Male
  • Familiarity:I've put it through the wringer

I picked up a RIP 9 in late July. With my old bike, I would ride trails once or twice a week. Since getting the Niner, I?m finding time to get out and ride more like 4 times a week. With the RIP 9, Niner has made a cutting-edge 29er trail bike that gets very close to the performance of carbon frames at a much more affordable price. The air-formed aluminum frame minimizes the weight penalty of aluminum, and the threaded bottom bracket and external fully-housed cables make setup and maintenance easy. Parts selection on Niner?s complete bike is incredibly good, comparable to a custom build. Some bike companies put downgraded parts where they might not be noticed, this bike is just the way a serious trail rider would want it. The only addition I made was a RockShox Reverb dropper post.

On the trail, the RIP does everything well. With the suspenson switched to firm, It has been equal to any uphill situation I have run into in Northern Utah. When the trail turns downhill, it is easy to reach down and open up the suspension on-the-fly and let the bike run. The bike is happy at moderate speeds, but does even better when it is ridden aggressively. It sticks to the trail leaned over down turns and switchbacks. It is easy to get the bike in the air off of medium jumps or drops, and landings are very manageable. On flowy ski resort trails, all-day alpine adventures, and night rides on neighborhood singletrack, this bike is big fun every time I take it out.

At 5?11? with a 32? inseam, I?m right on the line between Medium and Large. I went for the large. The bigger bike rides well in stock form, but I?d consider the shorter stem/wider bar combo that is increasing in popularity. Worth noting, the 38 mm reverb is the longest dropper post that works for a person my height in the large frame.

I?m available to answer questions about the RIP 9, or any other Niner bikes and products.

Medium Price, High Performance

Hi Mike,

Nice feedback on this RIP9. How is it since almost a year ?

Did you have the opportunity to ride the Tallboy LT ? How does it works compared to this RIP ?

Did you have any other 29er background ?



Hi Niki,

I rode the RIP 9 just this morning in Park City. I'm still loving it. It climbs as well as I could ask, and puts a smile on my face whenever i point it downhill. I have had a few rides on Competitive Cyclist's Tallboy LT Carbon Featured Mountain Bike in recent weeks. Both the Santa Cruz and the Niner are excellent Trail bikes, but I think the Niner is a little sharper handling and a better climber. With an extra centimeter of rear travel, The Tallboy LT suspension is more forgiving on fast descents. The Rip is capable of going as fast as I'm willing to push it, but requires a bit more input. To me, the Tallboy LT is more stable. The flipside of this is that the Rip 9 is more fun to climb and pedal on.

The purchase of the Rip9 last year was my move to big wheels, but before I picked it, I rode all of Competitive's full-suspension 29ers, including the Jet 9, Pivot Mach 429, Santa Cruz Tallboy LT, Yeti SB95, and Ibis Ripley. There's not a single bad bike in that bunch, but the aluminum Rip 9 hit a real sweet spot of fun, efficiency, and relative affordability that is not to be found with any of the other bikes I rode.
