Mojo 3 Carbon Mountain Bike Frame
The Mojo has been a stalwart frame in the Ibis lineup since the company's humble beginnings. We like to think of this latest version of the Mojo 3 Carbon Mountain Bike Frame as the definitive trail frame, from Ibis or otherwise. While not quite as burly as its enduro going HD4, the Mojo 3 is undoubtedly more versatile given its lighter weight, nimbler geometry numbers, and climb friendlier 130mm of travel. That's not to mention its ability to expand its horizon by handling standard and plus-sized tires, as well as single or double chainrings, letting you customize this Mojo 3 to suit your trail needs.
The Mojo 3's versatility is informed by the shock tune and DW-Link suspension. Ibis tunes the shock so its initial stroke rides on the "plush" side, but our firsthand experience with the bike tells us that generous small bump compliance doesn't keep it from feeling firm off the top. It's responsive and changes direction quickly while navigating switchbacks at climbing speeds, and the anti-squat pedaling platform maintains past the sag point. On the flip side, the ramp-up characteristics can best be described as the kind of big-hit confidence that can often be the key element in determining which side of the ragged edge you find yourself on. To cap it off, the shock tune and suspension keep the bottom bracket height at the sag point virtually the same, no matter what size tire you choose to run its only 2mm of difference.
The shock's tune doesn't require a high damper crutch, a fact that Ibis credits to the shock rate and DW-Link's steady pedaling platform. Since it naturally reduces bob without excessive damping from the shock, DW-Link's ramp-up stays smooth throughout its suspension arc. It also suffers less heat build-up than heavily dampened models, so its ramp feel isn't significantly affected during hard, fast descents where the shock is working overtime.
Ibis says that the stubby chainstays and low claimed frame weight make the bike feel "taut." We think that's a wonderfully succinct way to describe the responsive aggression the Mojo 3 exhibits on climbs that would send the lumbering gravity crowd in search of a chairlift. When paired with a 140mm fork, the Mojo 3's 66.8-degree head tube is almost on par with slack enduro standards and situates it squarely at the foremost tip of the advancing sea of all-mountain machines that drop in as well as they climb out.
One unfortunate side effect of this kind of trending super-trail geometry is that most slack, low bikes running five inches of rear travel and 27.5+ tires are also ditching the double drivetrain. But not the Mojo 3. Ibis insists that there's still a place for an extra chainring while navigating this brave new world of ever-overlapping boundaries, and the Mojo 3's removable front derailleur mount means you have options when choosing your build kit.
The frame itself is what you'd expect from Ibis: a full carbon monocoque affair that incorporates the construction pedigree of the HD4 but at drastic weight savings, shedding a claimed 0.9lbs compared to the enduro brute. The final product is actually the seventh carbon lay-up schedule that Ibis tested, yet another indication that the Mojo 3 was carefully and meticulously developed rather than being rushed to market in order to capitalize on the 27.5+ hype.
The tapered head tube further increases stiffness up front, which makes for yet better tracking across the terrain, and the inclusion of Boost rear spacing let Ibis slam the rear wheel up for the above-mentioned stubby stays which are approaching XC standards, while still leaving room for tubby tires and a front derailleur. That clearance also means that the frame is compatible with tires ranging from beefy 2.8in plus-sized down to 2.3in, though we see no reason to go below 2.4in tires given the Mojo 3's super trail pedigree.
