Greg,

Is the 'rubbing' continuous, or intermittent 'cricket chirp' type sound?

If it is continuous, try a few applications of the hand brake at 30 mph -- all the way down to zero. If it is still dragging after a cool-down ... readjustment is probably needed with more clearance -- just a couple of clicks.

If is is the cricket mating call ... the spiral guide for the cable is probably rubbing on the backside of one of the studs for the wheels. The cable will need to be readjusted and repositioned slightly.
