Are you feeling it through the frame? Avid brakes? Could be a couple of things - make sure the rear wheel is truly seated in the dropouts, the brake mount bolts are torqued to spec (Avid IIRC is 80 in-lbs). It may pay dividends to pull the rear caliper off - remove the pads, lightly sand the glazing off the pad surface, clean the rotor with rubbing alcohol and re-bed the rear brake.
I had some harmonic vibration on my Astrix Rook while using Juicy 7s on the rear - didn't get it with Hayes Nines. Just something about the rear Juicy 7, hub combination and frame that induced some harmonics.
