2024 Thunder Mountain RIPMO AF Shimano Deore X Large

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.
