Ripley NX Eagle Complete Mountain Bike

Even though mountain bikes continue to get longer and slacker, we think there's a point where it can go to far. There a balance that needs to be achieved, especially for trail bikes, and thankfully Ibis takes that into consideration with the new Ripley. Though the bike does get the requisite longer-slacker-steeper treatment to bring it into modern territory, we feel it hits a sweet spot that's still capable of quick accelerations and nimble handling. The bike gets a modest 1-degree slackening of the head tube angle, lengthening the wheelbase just a bit and extending the reach in the cockpit by 45mm to give you a little more room to move around. At the same time, the seat tube is 3-degrees steeper, providing a more comfortable and efficient pedaling position for attacking climbs and racking up the miles. The Ripley 4 also gets an all-new frame with design cues borrowed from the Ripmo, allowing room for longer-travel dropper posts, shorter chainstays, and providing a boost in stiffness—all while maintaining the liveliness and reliability of the DW-Link suspension platform.

The Ripley 4’s major redesign meant that Ibis’ engineers could start from the ground up, and they chose to start with the heart-and-center of the bike, updating the dual-eccentric links used in the past to a new design based on the Ripmo, which still holds DW-Link suspension tucked neatly in the front triangle, but without as much weight, and with a huge boost in stiffness. This change in the frame’s chassis allows massive weight savings of over a half-pound on the frame alone, giving your all-mountain machine a little more pep in its step when you’re pushing up grueling climbs, and a more nimble feel when you’re flicking it around tight switchbacks.

Weight savings aside, one of the biggest benefits we see with the drop of the double-eccentric design is extra room in the seat-tube, which enables taller riders to run dropper posts up to 185mm. This long-dropper length lets Ibis’ engineers carry forward with even more geometry tweaks, like an extra-low standover height, so you can pick your frame based on reach, eliminating seat-tube size from your list of limiting factors on your new-bike hunt.

Changes didn’t stop with the eccentrics though, the Ripley has been tweaked all over, including a one-degree slacker headtube for a stretched wheelbase that adds a bit of confidence to the descents, and a three-degree steeper seat tube angle that keeps you in the center of your cockpit perched nicely for climbs. On the rear end of things, Ibis shortened the chainstays by a whopping 12-millimeters to boost stiffness, and make the suspension a bit more progressive, without letting go of the lively pedaling characteristics of the previous Ripley.

  • Conquer the mountain with Ibis' speedy short-travel 29er
  • Modern geometry increases the bike's capability
  • Improved stability thanks to slightly slacker head tube
  • Steeper seat tube for more comfortable and efficient pedaling
  • Redesigned chassis boosts stiffness, drops 1/2-lb frame weight
  • New frame design allows room for longer travel dropper posts
  • DW-Link suspension is remarkably smooth and efficient
  • Short standover height enables you to fit bike based on reach

    everything about this bike is awesome!

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

    What can you say about one of the best everyday just crushing it mountain bikes? I’ve ridden the Ripley LS, Ripmo, HD3, HD4 and the HD5 and I have to say this new Ripley is a beast stuffed into a small travel frame. The wife and I traveled down to one of my favorite winter riding spots in Hurricane, Utah for a little winter camping and riding. I also thought while i’m demoing this sweet ride I’d also toss on one of the new Cane Creek Helm demo forks (140mm 44offset) and give that a shot as well. It’s been a while since I’ve been out on a bike, I’m coming back from an injury so the first day back riding and nothing seems out of the ordinary the bike simply works. It did feel a tad light on the front end on the steeper climbs, but that is most likely due to the fact that I had a longer fork on it. It wasn’t till the second day when the wife and I switched bikes and that’s when I really noticed just how sharp the front end handling was on the Ripley. Her bike felt lazy and sluggish in the turns and it definitely did not feel as efficient on the climbs or just riding down the normal trail. To be fair her bike has a little more travel but it’s still a 29” current model bike that we bought in March of 2019 when it first came out. I came away from the weekend incredibly impressed with the new Ripley. Ibis simply nailed the geometry and stiffness of this bike and the entire time while I was riding it I really couldn’t think of anything I wanted to change. I was going to drop the Helm down to a 130 travel fork on Saturday night, however I forgot to bring along my small bike washing kit and I didn’t want to get any dirt in the forks. If you are reading this review it means you are looking for a new ride and quite frankly if this bike isn’t on your short list, you need to reevaluate your list it’s just that good! What’s that you say, you don’t want to take my word for it? Well then feel free to email me at rojensen@competitivecyclist.com and I’ll check the demo tour in your area and we’ll get you out on one. Pros: Super Sharp handling Efficient pedaling Fits a huge range of dropper lengths for everyone Cons: Internal channeled cable routing is not good for running moto style braking (front brake on right) Tight rotor clearance so Hope floating rotors will be a problem Did I mention the internal sleeving (yes the bike is that good) Rider Details: 5'9" 32" inseam / 180 lbs Sag: 30% rear (seated) 20% front (standing) Version Ridden: GX Eagle w/ Factory shock option size Medium Upgraded * Cane Creek Helm 140 (up from OEM 130) Fork Upgraded * Magura MT Trail SL Brakeset Upgraded * SDG Radar saddle Pedals: Deity TMAC

    Best bike I've ever owned

    I've put it through the wringer

    Use at the mtn bike trails of Dallas/Ft Worth area, doesn't have the topography of Utah but not meek by any means. The bike climbs and descends equally well without all the extra travel that 90% of riders don't need anyway. The 29in wheels are nothing like the ones of old, this bike corners and snaps off of switchbacks just like my old 27.5 Trek. As far as the NX build goes i didnt see it as prudent to spend a ton more money just to shed a minimal amount of weight as I'm not an advanced rider but from a functionality standpoint the components work great. This bike seemed to be in very high demand and was unavailable at my local bike shops, Competitive Cyclist had it over a month earlier than was available locally. Arrived in perfect shape, just pop on the wheels and handlebars.

    How's the stability on descents? I wonder how it compares to the Ripmo. I know the Ripley can climb like a Rocket and pedals amazingly well, but it could be a bit more stable on descents.

    Hi jwi114060071, Sweet! Stoked to hear that you love your new ride! I just had our demo out and I couldn't be more impressed with a short travel 29" wheel bike.
