Bird is replacing its long-standing Aeris AM9 with an all-new long-travel 29er, more simply named the Aeris 9. Its ability to run 160-180mm of balanced front and rear wheel travel pushes it out of the all-mountain bracket and into the world of Enduro, or even Super Enduro.

It retains the familiar four-bar suspension platform and the reasonable pricing we’ve come to expect from Bird, adding a flip-chip at the chainstay to allow riders to run a longer or shorter rear-center length according to their preference.
