I' ll take this question!!! I have a Bear Whitetail II in my closet right now. It was one of the first (if not the first) cam bows to come out. Mine is a 70 lb and it has modules you can replace on the cams to adjust the draw length. Look at your cams and you should see the allen screws that hold the modules in place. I still have all my modules, though I use the 30" modules. I don' t know the brace height or axle to axle length, but I know I' ve gotten more deer with this bow than any other I' ve used to this day! With a 31" 2117 arrow, I could get 180-190 fps. That' s not much by today' s standard, but you don' t have to have the speed to hunt, you just have to be a good shot and skilled at getting close to game. I shot a young doe at 37 yards with this bow successfully, which is a testament to it' s accuracy.

BTW, as boldplate said, you never unstring a compound. Of course, if the string is frayed and worn you might want to replace it. For the price you paid (FREE), you have a great starter bow. If you need some draw length modules, drop me a note and I' ll send them to ya, as long as it' s not the 30" ones
