There are always going to be variables with this kind of testing. However, when you test enough bikes and components, you start to build a meaningful scientific baseline, and that can then be used to make better predictions about likely outcomes.

At this point, I would suggest that if the pitch of the aero bars is around 15 degrees, riding a mono-bar could potentially provide an aerodynamic advantage. My concern is that, as the mono-bar becomes more highly pitched, it could begin to act as a larger obstruction to the airflow rather than an aerodynamic benefit.

There is also another factor to consider: when you make such a significant change at the front of the bike, you inevitably influence the airflow and dynamics behind it. The front of the bike doesn't operate in isolation, so any substantial change needs to be considered as part of the entire system.

I would also encourage athletes to make the right choice when purchasing a mono cockpit. Yes, the carbon options can be expensive, but when they are designed and tested by a reputable manufacturer and used in accordance with the relevant manufacturer's regulations, they can provide a safe solution.

Ultimately, though, the front end of a bike is an area where safety has to take priority. You're dealing with a component that, in the event of a failure, has the potential to cause serious injury. For the sake of gaining a few watts, it may be worth looking at more cost-effective aerodynamic improvements elsewhere on the bike while keeping the risk as low as possible.

The fastest solution isn't always the one that produces the biggest number in isolation. It's the one that delivers a measurable gain while maintaining the reliability, handling and safety of the complete system.

The test subject wanted to identify the fastest BTS system on the market, EZ Gains totally embraced this challenge, it was important to test the most optimal set-up, so it could give a fair comparison.

Bottles Close to the Bum IS Faster, its not possible to do this with most other BTS units on the market, especially if you sit FORWARD on the saddle.

This was a bit of fun, but also an exercise to show YOU, the athletes, just how much of a difference aerodynamics can make. It’s something everyone can do to go faster without necessarily working harder.
So, next time you’re out cycling, have a think about the clothing you’re wearing and any flappy bits! Get them tucked up and keep things nice and aero.

Aero belly and boobs are good.
