Why We Like The Ripley Deore Mountain Bike

Contrary to the popular belief that 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 Ibis' newest iteration of its Ripley Deore 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 out for improved stability, lengthening the wheelbase just a touch and extending the reach in the cockpit 45mm to give you a little more room to move around. At the same time, the seat tube shifts up 3-degrees for the perfect perch when you need to attack climbs. The Ripley 4 also features an all-new chassis, taking queues from it's beefier sibling 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.

*Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.

Buying through Backcountry: Very pleased with my experience with Backcountry. Prompt delivery: bike arrived securely packaged, with just the handlebars to attach. With a torque wrench anyone can “assemble” these bikes. Gears and brakes were set up perfectly for a first ride. Local bike shops here have added a significant mark-up on most bikes, which is disappointing. Backcountry uses the RRP shown on the Ibis website. By becoming a member, I now have 15% discount coupon, and it appears I have accrued 25,000 reward points (pending) which I may be able to use to buy upgrades/kit/tools. After-sales service has also been excellent, and I’m very grateful to have had very rapid responses to questions from my personal Gearhead—Veronica—even through the busy Christmas period. Many thanks to the Backcountry team: I would highly recommend Backcountry for bike purchases. As for the bike… There a plenty of detailed reviews for this bike, so I’ll stick to key aspects. I’m coming from a lightweight XC hardtail, and enjoy challenging climbs and flowing descents with modest jumps, gaps, or drops. The scale of features I can manage has now greatly increased on this bike. The frame, shock, and fork are the same across the spec range, so although not cheap, the Deore level bike is pretty good value, including compared to most other in-store brands. Deore components work great; they’re just a bit heavy. The size Large is a good fit for my height (~178 cm with mtb shoes) and riding style (XC). The reach is quite long, but the stack is short compared to a lot of other bikes. The riding position is particularly good for seated climbs, but the short seat tube and long-travel dropper gives free movement around the saddle. In case it’s useful for sizing the RAD (BB to bar), is ~830 mm for this bike (with the stock 50 mm stem and bar). For me, the RAD would be ideally ~10-15 mm shorter, but I could remedy that with a shorter (30-35 mm) stem. The shock and fork are both Fox Factory, with the fork benefitting from a Grip2 damper. In terms of efficiency, I haven’t found a need for the shock lock-out switch yet. The manufacturer settings were a good place to start, but after a few weeks I’m still fine tuning. I’m finding it easy to overwhelm the travel on chunkier trails. This isn’t a complaint, given those trails are all labelled as “downhill”. Long term it’ll probably be worth exploring additional volume spacers to keep the plush small-bump control, whilst reducing the tendency to bottom-out. The Deore drivetrain and brakes have been great, but I have switched out some components. In particular, and for anyone thinking about doing the same, I’ve swapped out the derailleur and shifter for a SRAM GX AXS shifter and derailleur I already had, but I’ve kept the Deore cassette, crankset, and chain. Shift performance is still great. Better in fact: it's a bit quieter, and I haven’t had to make any changes since original set up and indexing. The only real let down is the dropper lever: it has a lot of play at its axle which means that the cable and lever rubs on the housing making it more difficult to activate. There’s some lateral play in the post, but otherwise the action is smooth. Adjustments for saddle position are very finicky and difficult to get right. In short though, I would strongly recommend the Ibis Ripley Deore build, as a cross country / trail bike that excels at climbs and high speed flow. It is sufficiently planted for my local trails, and has let me expand into trail segments I hadn’t tried before. The geometry is a good balance for climbs and descent, and the price point (again, not cheap) and rewards provided through Backcountry will have left me enough in reserve to change components over time to tailor the bike to a more personal fit.
