Mojo HD4 Carbon GX Eagle Complete Bike
Building upon the platform of the widely successful Mojo HD3, the HD4 goes into longer and slacker territory in order to bring greater confidence on the steep and fast terrain you'd find in the world's most challenging enduro races. The longer reach figures and slacker head tube angle help the bike attack descents with newfound haste, while the steeper seat tube angle and highly-efficient DW-Link suspension ensure you don't lose the remarkable pedaling performance and agile handling the HD3 was known for. Its development was driven by the needs of Ibis's professional enduro team, which piloted the bike to some stellar results in the EWS, walking away as the #1 ranked team shortly after the bike's initial release and proving just how awesome this bike truly is. And though Ibis recently released the HD5, it's not vastly different than the HD4—mostly just minor geometry tweaks, a revised shock tune, and a longer travel front fork. This means the two bikes perform very similarly, but the HD4 can be had without shelling out nearly as many of your hard-earned dollars.
Looking at the geometry of the HD4, you'll notice that the reach is substantially longer than it's predecessor the HD3. The longer reach gives Mojo HD4 riders a roomier cockpit so you can run a shorter stem and reap the benefits of a longer wheelbase for extra stability when you're pushing the bike to its limits on wide open descents. The bikes are now truer to size and you will not have to size up as Ibis noticed many riders did on past models. Lengthening the reach was one part of the equation for better enduro handling, and slackening the head tube angle is the other. Ibis experimented and did some real-world testing and found the perfect balance at 64.9-degrees. Ibis feels this angle maximizes stability in off-camber sections, increases maximum lean angle and allow rider's to carry greater speed through the chunder. We couldn't agree more. This bike loves to go fast and instills complete confidence when things get sketchy.
The Mojo HD4 retains the praised kinematics of the DW-Link platform. Very few suspension designs pedal this efficiently, attributable to the ideal anti-squat characteristics inherent to DW-Link. Throughout its travel, the feel is linear and very active when you need it to smooth rough stretches of trail, with enough ramp-up near the end of its travel to preserve that bottomless feel on bigger hits. Ibis increases the stiffness of the upper and lower links by 30 and 40%, respectively, significantly reducing rear end flex when pushing the bike hard on chunky terrain or when laying down a hard sprint at the end of a stage. Travel bumps up from 150 to 153mm, driven by Fox's excellent Float DPX2 rear shock. Modern enduro stages are essentially extended downhill runs, and the DPX2 offers smooth damping with a progressive end-stroke to prevent it from bottoming out on big hits and endless rock gardens. The addition of the reservoir allows for more adjustments and oil flow so the shock doesn't fade when ridden aggressively for longer periods of time.
Ibis continues its expert carbon frame construction with the Mojo HD4. The one-piece carbon lay-up results in a lightweight and strong frame with phenomenal stiffness, contributing to a responsive ride that tracks noticeably better than the HD3 in corners and rough terrain. A massive downtube guard keeps your investment safe from unruly rocks, while the molded swingarm protector all but silences chain slap. All sizes are designed to allow longer dropper posts than before, and the internal cable and dropper routing keeps the bike looking sharp. Lastly, the frame has clearance for up to 2.6in tires, meaning you can run some seriously high-volume rubber if desired.
