Sorry Uncle Cliffy and everyone else that keeps going off about the lack of shock options, but you may be proven wrong very soon. I have yet to see it in the flesh but I know a mech at my LBS who is throwing an Elka on his. I watched last week as he pulled the yoke assembly appart on mine to throw a Ti spring on and he showed me just how other shock friendly it is. Apparently many other manufacturer's coil shocks will also mount up as long as you pop the DU.
