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 our long tenure from moun?tain biking's awk?ward ado?les?cence to its cur?rent any?thing-shred?dy era, we've exper?i?ment?ed with steel, alu?minum and tita?ni?um?--?remem?ber the Bow-Ti, the first super?bike? We remem?ber the met?al times too, and it feels good to offer a pre?mi?um ride expe?ri?ence to our broad?en?ing fam?ily of rid?ers, cour?tesy of durable, afford?able alu?minum alloy. Universal Derailleur Hanger The Rip?mo AF UDH fea?tures a UDH derailleur for max?i?mum future com?pat?i?bil?i?ty and moves to a 55mm chain line. The wider chain line allows for a stiffer chainstay. Modern Geometry With a steep, 76-degree seat tube angle and a rangy but not stratos?pher?ic reach, the Rip?mo AF places rid?ers cen?tral?ly and upright over the bot?tom brack?et. It makes for an effi?cient posi?tion that can go the long haul with?out plac?ing too much weight on its slack, 64.9-degree head?tube angle. A 44mm reduced-off?set fork is more sure?foot?ed on steep descents and stead?ies high speeds. Bet?ter up, bet?ter down. DW Link Since 2005, we've part?nered with sus?pen?sion guru Dave Wea?gle on the dw-link sus?pen?sion plat?form. It pro?vides an unpar?al?leled com?bi?na?tion of climb?ing effi?cien?cy and down?hill per?for?mance, which has been proven repeat?ed?ly at the high?est lev?els of racing. Air & Coil Compatible The Rip?mo AF is com?pat?i?ble with both coil and air shocks due to a more pro?gres?sive lever?age rate. It allows for coil's lin?ear?i?ty to thrive and we spec air shocks with tunes that pro?vide pop with?out feel?ing too harsh. On the trail, it gives the sus?pen?sion a sup?ple feel through?out the entire?ty of the stroke, enhanc?ing trac?tion no mat?ter how deep you dig. 2.6" Tire Clearance Ibis helped pio?neer the wide rim rev?o?lu?tion, which inspired the new crop of wider 2.4"?--?2.6" tires. When paired togeth?er, this com?bo can be run at ultra low pres?sures which results in elbow-drag?ging cor?ner?ing trac?tion with?out sac?ri?fic?ing straight line speed. Pick Your Size We use words like small, medi?um, and large to describe our siz?ing because it's easy to under?stand, but our ultra low stan?dovers give you the abil?i?ty to size your frame based on reach and preference. Long Dropper Post What's bet?ter than a drop?per post? A longer one. Our frames are designed to accom?mo?date the longest drop?per posts pos?si?ble. Rid?ers over 5'8 (or 173cm) can eas?i?ly run a 185mm drop?per post, while folks between 5' and 5'8 (152cm?--?172cm) can use a post 125mm or longer depend?ing on inseam length. Removable ISCG05 Mount Our option?al ISCG 05 mount is there if you want it, remov?able if you don't. Seven Year Warranty We stand behind our prod?ucts. If it's our fault, we'll fix it. Our alu?minum frames are backed by the same 7 year war?ran?ty and excel?lent cus?tomer ser?vice as our car?bon products.
