If you study the shimano line up youll see many little differences that all add cost and shave a little weight Is the top tier price justified? I dunno, possibly not. Imo the real difference in disc vs rim, mech vs electronic, power meter vs no power meter, etc ...Much more so than 105 vs Ultegra in the same configuration.
