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.
