The Ripmo AF (Aluminum Frame) brings the award-winning performance of the carbon Ripmo to a wider, rowdier audience. It’s everything we love from the carbon Ripmo, plus a few tweaks.
IT’S METAL
Over IBIS's long tenure from mountain biking’s awkward adolescence to their current anything-shreddy era, they’ve experimented with steel, aluminum, and titanium — remember the Bow-Ti, the first superbike? They remember the metal times too, and they are stoked to offer a premium ride experience to a broadening family of riders, courtesy of durable, affordable aluminum alloy.
MODERN GEOMETRY
With a steep, 76-degree seat tube angle and a rangy but not stratospheric reach, the Ripmo AF places riders centrally and upright over the bottom bracket. It makes for an efficient position that can go the long haul without placing too much weight on its slack, 64. 9‑degree headtube angle. A 44mm reduced-offset fork is more surefooted on steep descents and steadies high speeds. Better up, better down.
AIR & COIL COMPATIBLE
The Ripmo AF is compatible with both coil and air shocks due to a more progressive leverage rate. It allows for coil’s linearity to thrive, and spec air shocks with tunes that provide pop without feeling too harsh. On the trail, it gives the suspension a supple feel throughout the entirety of the stroke, enhancing traction no matter how deep you dig.
