If you like to punish yourself on a hard tail than the IBIS Cycles DV9 may be the ultimate bike for you. At just under a $1000 for the frame only it makes this a great option to build up a carbon hard tail. With 29er wheels, a 100mm or 120mm fork option, and the ability to 2.6 tires it will make for one heck of a rocket ship on the trail. As Jeff puts it this a playful bike for jibbing and launching off jumps!
