Prototype Deity Cryptkeeper Dirt Jump Frame

"What you see here is our first prototype and we are already making some subtle changes for the frames you will see at the end of the year. The Cryptkeeper will also be joined by our upcoming street specific frame, the Streetsweeper which, like the Cryptkeeper, will be designed to focus on the needs of dedicated street/park riders. The needs of a dirt jumper and the needs of the street rider in terms of frame design are two different worlds and must be treated as such.
We wanted to create a true aggressive dedicated dirt jump bike with the Cryptkeeper. Our focus started with BB height issues which all center around a frames "BB Drop". This is the center point of where the BB shell sits in line with the center point of the wheel axles. By using a 25mm BB drop, we are able to get the center of gravity lower without sacrificing maneuverability of the front end off the ground. By using super-short 15.25" chainstays, the bike is able to accelerate extremely fast out of berms and by being balanced with a 22.25" top tube length, the rider is directly centered on the bike making its handling extremely predictable.
