I answered the thread earlier, but I just realized the real breaking point for me - bibs. A solution to a problem that already had a working solution and this new one added another. So I never jumped on board. (Clip on suspenders. They allow for bodily functions that affect some of us without requiring contortions. Learned about them from the racing guru of Boston in 1976. John Allis.)
So I am officially a retro. Got most of the rest of the gear, but just one pair of old bibs
