It's no coincidence that Ibis cheekily named this bike the Ripmo. It is truly a crossover bike, blurring the lines between their wildly popular Ripley 29" trail bike and their much more aggressive Mojo HD4 enduro bike. The Ripmo takes everything we love about these two bikes and blends them together into one glorious package. It's the lovechild that we've been wanting from Ibis for years, and there are several key features that make this a dang exciting bike.
Ibis opted for 145mm rear suspension travel, built around the tried-and-true dw-link platform, now in it's fifth iteration. Up front, the Ripmo is intended to be used with a 160mm travel fork, though you can go 150mm if so desired. New to this bike, Ibis opted for a reduced 44mm offset fork, similar to what Transition is doing with their SBG bikes. This allows for increased reach/top-tube lengths while still being able to reign in the wheelbase by bringing that front wheel back with the reduced offset. The head tube angle sits at a relaxed 65.9º, which is right on the money for most riders. It's not quite as slack as something like the Transition Sentinel, but that's not necessarily a bad thing. While super slack head tube angles are great for crazy gnarly/steep descents, they are not so great when it comes time to climb. Ibis wanted to make sure the Ripmo was a well balanced bike, able to descend and climb confidently. Speaking of climbing, the Ripmo gets a nice steep 76º seat tube angle, which we're very glad to see. This puts you in a great forward position when seated on the bike, pedaling up hills.
Standover clearance on the Ripmo is great, thanks to a low-slung top tube and short seat tube. Ibis has also made sure to maximize seat tube bore depth, allowing folks to run long-travel dropper posts - up to 150mm on the small, and 175mm + on the MD, LG, and XL sizes.
Ibis has always been a strong proponent of wide rims and wide tires, so it comes as no surprise that the Ripmo is fully compatible with tires up to 2.6". Mount them up to 35mm ID rims, and you'll still have plenty of clearance for mud - oh yea, and traction for DAYS!
The Ripmo is equipped with fully guided internal cable routing. That means you stick a cable in one end, push it, and poof, it comes out exactly where its supposed to. No fishing for cables inside the frame. Ibis has made use of a combination of bearings and bushings on this frame. If used in the right places, bushings are actually lower maintenance, stiffer, lighter, and more affordable than bearings. Bushings work better than ball bearings in applications with high loads and minimal rotation, which describes most mountain bike pivots.
Far beyond the testing phase, Ibis has used bushings for the past five years on the Ripley, HD3, and HD4 clevises. High loads and minimal rotation describe the Ripmo lower link pivots so they've introducing a new link featuring IGUS bushings. The new link is 80g lighter than its ball bearing equipped equivalent, while also being torsionally stiffer. The bushings are shielded from spray and protected by airtight seals and will last a long time. Ibis is so confident in their bushing/bearing system that they are offering free lifetime replacements.
Other details on the Ripmo include a threaded 73mm BB shell, a ZS44/ZS56mm headtube, removable ISCG '05 chainguide tab, 12x148mm Boost rear dropout spacing, and ample clearance for a full-sized water bottle in the front triangle.
As with all Ibis products, the Ripmo is backed by Ibis' 7-year warranty.
