Bike Check - Ibis Mojo HD4

Longer, slacker, and more aggressive. While Ibis has kept the rear travel and wheel-size consistent between the HD3 and the HD4 (153mm and 27.5-inches, respectively), that’s about all they left untouched. The HD4’s head angle is slackened out to 64.9°, the chainstays stretched to 16.9”, the seat tube angle slightly steepened to 74°, and the leverage curve is now more progressive, putting the bike in the realm of most current mid-travel enduro bikes. This custom build we just finished up came out stellar! Be sure to check out Pinkbike’s in-depth review of the HD4 to learn about all the updates Ibis has made to the HD platform.
