Ripley NX Eagle Complete Mountain Bike
Contrary to the popular belief that all mountain bikes should be as long and slack as possible, we think that there’s a balance to be achieved — especially in the trail-bike department. Though the Ibis’ newest iteration of its Ripley NX Eagle Complete Mountain Bike does see a full redesign that does include the modern longer-slacker-steeper treatment, we think it finds a moderate landing place that’s still capable of quick-rolling power and nimble control. That’s because the engineers at Ibis didn’t go too overboard — instead they opt for just a one-degree shift in the head tube to slacken things, lengthening the wheelbase just a touch to extend the reach in the cockpit 45mm to give you a little more room to move around, while the seat tube shifts up 3-degrees for the perfect perch when you need to attack climbs. The Ripley 4 features an all-new chassis, taking queues from it’s beefier brother, the Ripmo, offering more room for dropper posts, shorter chainstays, and the lively and reliable DW-link suspension.
The Ripley 4’s major update 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-eccentrics 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.

Plush XC Racer?
- Familiarity: I've put it through the wringer
First off, my purchase experience with CC was excellent, from the person on the phone who took my order, to the packaging of the bike.
Regarding the Ripley, the bike is phenomenal, even the NX build. It rides like a plush xc race bike. Excellent climber, and very fun on the descents. I plan on swapping out the Level brakes for XTs on my previous bike, and ultimately the NX drivetrain (when it wears out) with XT 12 speed. (No issues with Level brakes and NX drivetrain, just a preference towards XT, especially the brakes).
UPDATE: The Level brakes needed to be bled after ~100 miles so I swapped them out with XT brakes. Routing the rear brake line through the internal routing was a breeze. It took all of 10 seconds to push the brake line through!
Aside from the weight, which I probably dont notice while riding, the NX drivetrain is pretty good and does what its supposed to.
