Like new Salsa Cassidy aluminum frame with upgraded shock and head set Frame has maybe 10 hours on it. Shock has 0 hours. This thing RIPS. With split pivot you can change the rear shock and linkage and turn this into the Blackthorn. You also have you setting for the rear shock, High and low. Easily change the geo and handling of the bike with a simple flip of a insert. I rode this bike a handful of times while waiting for the carbon version to come in. By far one of the best full suspension bikes I have ridden. I ran mine with a 165mm travel fork as I prefer a more even set up. Cassidy's come out of the box with 165 rear and 180 front travel. This thing did not climb like it had 165mm of rear travel though. It climbed great and descended any level trail I threw at it with ease. Comes with an upgraded Cane Creek 40 headset. Has ISG mounts and a BSA threaded BB. Rear Spacing is Super Boost. Chain stays are short and add to this bikes fantastic handling. Internal routing for brake lines, shifting and dropper. This is a size Small. I am 5'8" and it fit me like a glove. I was on a medium Trek prior. The Fox Factory X2 rear shock is brand new, never ridden. This is the shock that comes on their carbon frame. With independent High and Low speed compression adjustments you can dial this shock in for you specific riding style. Any questions please feel free to ask. Sold as is and come with headset, rear axle and der hanger. I do have a brand new set of DT Swiss 240 32H hubs that I was going to lace up for this build (ended up going with Profile Racing hubs) that I can include for an additional $600. Frame will be professionally packed and shipped VIA UPS or USPS with signature confirmation through my local bike shop. Packing and shipping will be $150 to the lower 48 only free pick up is also available. Don't miss out on this deal. Your essentially paying the aluminum frame price and getting a free $700 rear shock!!!!
