The bike came with a Ritchey Logic headset that needed to be overhauled. The ball bearings were loose in the cages so I put new bearings in without the cages. Put a proper spacer in so it didnt bottom out. A month later it has become loose again. Do I readjust it again or just buy a new one? If so what would work? I was looking at this:
