I watched the 2019 Masters stuff while I was on the trainer last night. Some of those 50-54 guys are really fast. 34.5s 500m.
One thing I noticed is that almost none of them used aero bars. They used drop bars instead. This was indoors, so front disc, and presumably less wind. I wonder if outdoors, with wind, maybe a multispoke front wheel?, if more racers would use aero bars.
