Sorry I missed this. If we are both looking at the bolted on polished metal piece betwixt stem and HS top cap it is a proprietary structural mount for the front rack.

Hopefully GC didn't think I was being too hard on him to make a very sensible safety related point. IAB at least offers nothing to physically hold onto that would delay the correct decision to return to the hoods in an emergency. Or worse cause bodily injury neatly endoing into a pile of crashed riders.
