First Look: Ibis HD5

Updated geo and new shock tunes for this EWS-winning platform

27.5 News

Ibis has been on a tear this year. For a small company, rolling out three new bikes in a single season is no small feat. First, it was the short-travel Ripley; then, a longer, slacker, aluminum version of the Ripmo; and now, a revamped version of the company’s 27.5-inch enduro machine, the HD5.

Ibis HD5 Highlights

  • 170mm front travel/153mm rear travel

Up to speed for aggressive riding

A great deal has changed since Ibis released the EWS-winning HD4 in 2017. Reach measurements grew, seat tubes became steeper, and head tube angles grew ever slacker.

The HD5 follows suit with these geometry trends with a 2-degree steeper seat tube angle, 17mm of extended reach on a size large, and a slightly slacker, 64.2-degree head tube angle when paired with a 170mm fork, versus the 160mm model that came stock on the HD4.

In updating the platform, Ibis took note of how many of the company’s sponsored enduro racers set up their HD4s and made updates to reflect these preferences. These changes include spec’ing a longer, 170mm suspension fork and increased stack heights. Ibis also reduced the seat tube lengths across all four frame sizes to fit longer-stroke dropper seatposts. Medium frames will accommodate 175mm droppers, while smalls with fit 150mm models.

 

Suspension updates

Ibis used the same matched suspension philosophy it developed for the Ripmo. In the case of both of these models, the actual vertical suspension travel of the fork ( measured vertically from the fork’s axle, as opposed to in-line with the fork’s stanchions) is matched by the bike’s rear suspension. In the case of the HD5, that number is 153mm of suspension travel. According to Ibis, this approach provides a balanced suspension feel, resulting in more predictable handling.

There’s another important suspension change at the rear of the HD5. Ibis worked closely with the suspension engineers at Fox to develop a suspension tune that’s a better fit for the company’s dw-link suspension design.

This “Traction Tune” suspension uses extra-light high-speed compression- and rebound-damping to create a more usable range of suspension adjustments and improve small-bump sensitivity. This tune will make its way throughout the rest of the company’s line-up this fall. Existing Ibis owners can ask for this suspension revavle when they send their shocks in for service with Fox.

Like the Ripmo and Ripmo AF, the HD5 uses IGUS bushings in the lower link and clevis in place of the bearings used in the HD4. As with the models mentioned above, these sealed bushings come with a lifetime warranty.

Ibis HD5 pricing, weights and availability

 The HD5 frame with Fox Float PDX2 shock retails for a very palatable $2,999. Complete builds start at $4,399.

The HD5 frame without shock has a claimed weight of just 5.6-pounds. Complete builds have a claimed weight as low as 28-pounds.

If you’re reading this, the HD5 is ready to buy.

    Ibis worked with Motion Instruments, not Fox. Data gathered using Motion Instruments sensors were analyzed by Ibis suspension engineers and spec’d Fox with tune they required.
