MOJO HD GENERATION 3
The new Mojo HD (HD3 for short) is the third act in the Mojo HD/Mojo HDR trailbike trilogy. Everything is new from the ground-up, notably featuring the latest and greatest refinement of the famed dw-link suspension. Geometry is fully modern: longer, lower and slacker, with 6” of plush rear wheel travel. We’ve built in versatile internal routing and updated the frame design, allowing us to put a water bottle on top of the downtube. We also achieve a drop in weight and pedaling performance on par with the Ripley, so the bike is very fast going up, and scary fast going down.

“Progress is not in enhancing what is, but in advancing toward what will be.”
Since the introduction of the revolutionary Mojo Carbon in 2005, we always have “moved toward what will be” made bike in the balance between skills and pedalability.
The final result is the third generation of the Mojo HD (HD3), an extremely long travel bike that can do it all.
“Hundreds of kilometers on the new Mojo has shown it to be more capable on the descents than its predecessor, but without many of the drawbacks that often come with such impressive abilities. Ibis has done well by taking the phrase ‘all-around’ to the next level.”
Mike Levy – Pinkbike
What’s most amazing about the HD3 is that with the help of the latest and best ever refinement of the dw-link, we’ve managed to completely decouple pedaling performance from suspension travel. That means that our 6” bike probably climbs better than a lot of 4” bikes. And due to the descending credentials of the dw-link, it probably feels like your 7” bike when you point it down hill and let go of the brakes.
“Ibis has simply made one of the best-balanced all-mountain bikes on the market.
Vernon Felton” – Bike Magazine
While the frame looks similar to its predecessor cousins the HD and the HDR, the geometry has been refined and modernized. All top tube lengths have jumped by 20mm from the earlier HD’s. The bike is longer and lower and slacker. With the Fox 36, you can build the bike of the beast with a 66.6º head angle. The Pike fork with 150mm of travel delivers a 67º head. The upright seat angle (73º) and short (16.9”) chainstays helps us make the bike into such a capable climber (see quotes above).
We think 6” of travel is right for most people’s riding needs, we felt it struck the best balance for a climbable enduro style bike. With a longer travel bike comes the temptation to put 180mm forks on them, thus requiring heavier frame construction and moving the bike into a different category.
Variable leverage rates and shock tunes can make a 6” bike feel it’s got much more travel, or it can be the other way around. Since our dw-link bikes tend not to get stuck in the middle of their travel and have a very linear feel to them, the available travel feels consistent, predictable and more usable.
Another advantage of sitting a bit higher in its travel is that we can lower the bottom bracket height, making for a better handling bike, while not being prone to pedal strikes.
You’ll notice that the HD3 shares its DNA with the Mojo HD, the Ripley and the Tranny. From the HD comes the iconic Mojo frame design, beautifully organic yet proven to be fiercely robust. We’ve borrowed the clevis idea from the Ripley, allowing for more clearance in the triangle, meaning you can conventionally mount a water bottle inside the triangle (and another one under the downtube on the large and XL). From the Tranny comes the latest in elegant industrial design and versatile cable routing options.
We’ve managed to keep the weight to less than 6 pounds with shock (5.9 with a large size).
With the help of the clevis, we’ve made the linkages on the HD3 lighter. There is a new bearing configuration, with both dual row angular contact bearings moving to the drive side, enhancing the stiffness.
As with the Ripley and HDR, we start by molding a sacrificial mandrel in exactly the shape that we want the inside of the frame to be. That becomes the 3D template for the bladder that holds all the carbon preform before it’s laid into the mold. This allows the lay-up to be done in one piece, with no joints anywhere. The result is a more precise structure that eliminates the need for additional foam or filler to mold the complex shapes. What that means for you is a lighter and stronger frame, critical factors in hitting our targets for weight and stiffness.
We offer both the Float CTD and the DBinline on the bike. We think the CTD is an extremely reliable, light, capable shock that is a great choice for a lot of people. For more aggressive riding and greater tunability, there’s the excellent and robust DBinline.
The tune on the Fox is 175 boost medium compression/ medium rebound. The low boost valve gives us better small bump sensitivity and then the medium compression tune takes over for bigger hits.
The goal with the dw-link tune on this bike is to pedal well and have even better small bump sensitivity. The leverage rate delivers the same linear feel with a slight ramp at the end that we’ve always liked. This keeps the suspension feeling consistent and predictable, with no nasty surprises.
To setup sag, go for 14 – 18mm / 25 – 30%.
We run tapered head tubes and steerers in all of our bikes as they deliver an exceptionally rigid front-end platform. One of the new features of the HD3 not found in our bikes previously is the ZS56 lower headset. This allows for a bigger gap between the top tube and the down tube which results in a stronger front end with no weight penalty. It’s particularly effective on the small and medium.
You may use several different Cane Creek headsets or the Chris King InSet 2 headset.
There’s a lot of versatility with the cable routing. You can run full housing or interrupted housing. Interrupted housing using our available cable stops will allow you to save about 55 grams of weight over a fully run housing. Our dropper of choice is the KS LEV Integra but a dropper line can be run though the top tube if you’re not using a top pull front derailleur.
FRONT DERAILLEURS AREN’T DEAD YET
If you peek under the upper link at the back of the seat tube, you’ll see a small aluminum piece bolted on. That’s a cover plate that replaces our direct mount front derailleur adapter. If you’re running 1X you’ll use this plate, and if you want to run XTR 2X or XT 2X, there’s an extremely clean derailleur mount that bolts on.
The bottom bracket is threaded 68mm with ISCG capability. Each frame will ship with an adapter, allowing you to mount a chainguide should you desire.
TIRES AND ROTORS
Depending on brand and depth of knobs, most 650b tires up to 2.4″ will fit the Mojo HD3, and you can fit up to a 200mm diameter rear rotor.
POLYCARBONATE DOWNTUBE GUARD
If you ride in rocky environments we have available an optional polycarbonate guard that bolts on under the down tube, providing an extra degree of protection.
