Unlike recumbents where there are real choices/differences in riding
position, seat type, steering arrangement, etc. [1], upright road bikes
tend to be much the same. Therefore, marketing departments have to come
up "reasons" for riders to invest in new equipment on a regular basis,
whether or not it is warranted.

[1] There have been real improvements on a fairly consistent basis in
recumbent bicycles over the last 20 years, including a great refinement
of the classic designs that have been around over that time period (Easy
Racers Tour Easy, Lightning P-38, RANS Stratus, Ryan Vanguard/Longbikes
Slipstream).
