Terrain

Built for the trails, the HD4 has 27.5” wheels and an incredible 153mm (6 inches) of rear wheel travel — this is accomplished by the addition of the latest model of the dw-link suspension design used in this fourth gen bike.

The company, Ibis Cycles, stated that they built “on the success of the HD3 and its predecessors” but the HD4 “has been further refined and optimized to handle the steepest, most aggressive terrain found worldwide. Testing [was conducted] throughout Northern California’s most rugged backcountry trails and also by members of our Enduro Series team.”

Increase in Size Range

Finally — the HD4 is now suitable for a wider range of riders. This new model has a slacker, 64.5 degree headtube angle — which increases the size range.

Design Changes

In addition to the 27.5” wheels and 150mm of rear wheel travel, Ibis also claims that the suspension linkages are stiffer. The company also shortened the seat tube height and increase its bore depth to allow longer-drop dropper posts.

The HD4 also features an increase in shock leverage curve, which will give riders a better huge hit performance. The re-engineered carbon layup is also perfect for adding greater frame stiffness overall.

Breakdown

The HD4 now features a completely new geometry design, with a focus on speed and stability for the roughest of trails. With big-hit performance through increased progression in the shock tube and and a 64.9 degree head tube angle, this bike can accommodate a greater reach across the board (4mm on a small and up to 34mm on an extra large).

travel air time

With compatibility for the longest droppers and a carbon layup, which yields superior stiffness, you can customize and ride the trails your way. 30 percent stiffer upper link and 40 percent stiffer lower link.

This fourth generation model uses Dave’s most efficient system to day: the dw-link v5 kinematics.

As for the headset, Ibis uses the ZS56 lower headset. This allows a greater gap between the top and down tube, which makes the front end stronger with no penalty on weight. You can use different Cane Creek headsets or the Chris King InSet 2 headset.

Linkages

The routing is also extremely versatile thanks to the cable port system. You can run full housing or interrupted housing — interrupted housing using Ibis’s available cable stops will save 55 grams in weight over a fully run housing, if that helps.

The shocks — the 2018 shock that comes with this model is available in the HD4 NX kit that arrives June 13th. It is a custom tune designed especially for this bike and is a new shock. An upgrade is available for shocks on every kit, such as the 2018 Factory Series Fox Float X2 with Kashima coating. On both shocks, Ibis engineered more progression into the shock leverage curve, which will give you big air time and big-hit capability in some tough terrain. To setup sag, go for 14 — 18mm / 25 percent — 30 percent.

Shocks

And the wheels — well, this Mojo HD can fit a tire up to 2.8 inches on the 27.5 inch wheels. You’ll have a blast on this trail bike by Ibis.
