– These numbers are calculated for a rider over 40kms at a time of 48minutes. Faster than most of us could go!
Here's the article. As someone else pointed out, it's fairly old and maybe the precise numbers can be argued with. https://cyclingtips.com/2010/04/bigg...ial-equipment/

Your "yeah but..." post shows you have a pathological compulsion to point out shortcomings of a bike you don't ride by pointing out something that isn't even part of the discussion. I think the pot is calling the kettle black in your case.

More recent wind tunnel tests confirm the differences clothing can make. When Oliver Bridgewood tackled the one hour record a few months ago they demonstrated a lot of testing in the GCN videos leading up to that effort. Very relatable stuff since Ollie is a cycling enthusiast, not a pro. (Better than Ollie's previous aero demo videos with Cycling Weekly, possibly due to GCN having a bigger budget.)
While I wasn't ready for an off the rack skinsuit, let alone the custom job Ollie was fitted for, that series of videos did persuade me to get some snugger fitting sorta-aero jerseys and one of those rounded sorta-aero helmets (no fins, thanks). It helped. Cheap and easy fix.

Specialized built and operates its own wind tunnel. IMO, they do a great job discussing and quantifying what an aero upgrade is worth by running tests in the tunnel. They have a number videos discussing other aero effects. Search Specialized Win Tunnel on YouTube to see them all.

How fast do you ride?
15 MPH is the approximate speed at which aero drag surpasses all of the other drag factors on a bicycle combined. If you typically ride more slowly than 15 MPH, aero drag improvement isn't going to help you very much. If you ride faster than 15 MPH, the faster you go the more significant aero drag factors become.
