Ibis Ripmo AF UDH GX

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.

Over our long tenure from mountain biking’s awkward adolescence to its current anything-shreddy era, we’ve experimented with steel, aluminum and titanium—remember the Bow-Ti, the first superbike? We remember the metal times too, and it feels good to offer a premium ride experience to our broadening family of riders, courtesy of durable, affordable aluminum alloy.

The Rip­mo AF UDH fea­tures a UDH derailleur for max­i­mum future com­pat­i­bil­i­ty and moves to a 55mm chain line. The wider chain line allows for a stiffer chainstay.

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.

Since 2005, we’ve part­nered with sus­pen­sion guru Dave Wea­gle on the dw-link sus­pen­sion plat­form. It pro­vides an unpar­al­leled com­bi­na­tion of climb­ing effi­cien­cy and down­hill per­for­mance, which has been proven repeat­ed­ly at the high­est lev­els of racing.

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 we 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.

Ibis helped pio­neer the wide rim rev­o­lu­tion, which inspired the new crop of wider 2.4” — 2.6” tires. When paired togeth­er, this com­bo can be run at ultra low pres­sures which results in elbow-drag­ging cor­ner­ing trac­tion with­out sac­ri­fic­ing straight line speed.

We use words like small, medi­um, and large to describe our siz­ing because it’s easy to under­stand, but our ultra low stan­dovers give you the abil­i­ty to size your frame based on reach and preference.

What’s better than a dropper post? A longer one. Our frames are designed to accommodate the longest dropper posts possible. Riders over 5’8 (or 173cm) can easily run a 185mm dropper post, while folks between 5’ and 5’8 (152cm - 172cm) can use a post 125mm or longer depending on inseam length.
