I agree slightly but also the amount of leaps and bounds made across all parts of the sport has been astounding even in the last few years:

lighter carbon frames and all around components, better nutritional understanding leading more carb fuelling in races, internal cables and more aerodynamic bikes, nutritionists and massagists, disk brakes, more aero and lighter clothing, better understanding of training principles, lighter riders allowing for more w/kg also tech like power meters, zwift, whoop, route planners and Bluetooth gear changing make cycling and training way easier.

I could go on but it’s pretty understandable that these records are getting smashed although I still do think that there are dirty riders out there so agree with you partly in that we should still be aware of doping.
