Yes, there is. Oversized, carbon, Ti, etc cages and jockey wheels are available from $50 to $600. Ceramic and exotic bearings are out there.
Ceramic Speed, for example, will sell you that 2 watts at the RD for $600. You can add some more watts with their BB bearings for $600 more. Custom hubs have already been around for a while. Carbon chain rings are coming out, short term, short range.
The weight arms race is sort of over, given the ease with which 15.1 is reached. The UCI could change this tomorrow.
The next areas are aero, friction mitigation and where on the bike to put the 15.1 pounds, be it in rotational mass, or not.
