2023 World TT Championship / UCI Rules
I noticed that some riders (notably Evenepoel and Van Aert) had what appeared to be a bottle or other container in the chest area of their skinsuit. This has been a trend recently in triathlon, but unless I'm mistaken, UCI rules forbid it. There are rules against wearing hydration systems on the front of the rider and rules against adding items or clothing which serve no other purpose than to alter body morphology / improve aerodynamics. Am I missing something or is the UCI turning a blind eye?

You're missing something. It was a race radio (with, presumably, a lot of padding or something for "safety") which is allowed.

I'd seen this article claiming it was a water bottle, so I guessed it was something of that nature. Either way, the size and placement seem to violate the spirit of some of the UCI rules, so it's strange that they would allow it. Doesn't make sense that a race radio is allowed to be used to improve aerodynamics, but a water bottle isn't. |

I haven't visited Bike forums in a while, but good to see the ******baggery lives on here.

How likely is it that both Remco and WVA would blatantly cheat in a way that is visible to everyone and hope to somehow get away with it for a gain of a few seconds? Whatever they did, the Belgium team certainly cleared it with the race officials beforehand. |

Whatever they did, the Belgium team certainly cleared it with the race officials beforehand. Regarding the potential gain: as I mentioned, putting a water bottle down the jersey is currently a trend in triathlon. It has been tested and a 28oz bottle can result in a 2-7% drag reduction. I didn't do extensive math, but at the duration of this event, even a 1-2% drag reduction would have made the difference between the top 2 spots. |
Great topic. It reminded me of this, arguably similar contretemps.

If a water bottle is good for 2-7% I can't imagine the gain that I get from my gut ! WOW !

Fair enough, I guess.
My point isn't to accuse those 2 riders of cheating, but I used them as examples because they were the most obvious cases. I wouldn't assume that they cleared it with officials. There have been times in the past where things like this were only called into question after the fact. Anyway, if the UCI's stance is that it's OK, then it is inconsistent with their rules regarding hydration and clothing alterations. It's clearly done for an aero advantage and the "safety" argument doesn't hold up. If safety is a concern, then not using the radio would be best. https://www.facebook.com/groups/1421...2520804394762/ or: https://www.cyclingnews.com/news/wha...ay-time-trial/ No one, in any official capacity, is complaining about this. If there was something there, they would be. Italy would be screaming at the top of their lungs if this was in any way questionable. You'll also note in the linked article Alex Dowsett says "The UCI do all the checks. We spend 15-20 minutes with them before the start. They check the bikes before we come to the start as well. They look us up and down, and at the end of the day they let us roll down the start ramp or they don't."

It's not inconsistent. Radios are allowed.
Hydration is an essential physiological consideration for athletes during a physical effort. Neither bottles nor camelback systems should diverge from their original function. There is a significant risk of camelback systems or any similar devices being used for other purposes than their original function. For this reason certain restrictions apply if they are to be used in competition: •The camelback system is authorized for competition solely for the purpose of rehydrating the rider. •It must not be the case that the system, presented as a way of improving a rider's hydration during an effort, is accompanied by an "aerodynamic clothing" advantage, in this way deflecting the camelback system from its original function. •The liquid container must not be capable of holding more than 0.5 liters and must not be a rigid shape liable to be considered as a device for improving the rider’s aerodynamic qualities. •The use of the camelback system must not modify the rider's morphology and must thus be directly attached against the body. •The use of the camelback system is only allowed on the back of the rider. It is mandatory for all riders who want to use a camelback system to present it to the commissaires before the start of the race at the risk of being disqualified. Items of clothing may not modify the morphology of the rider and any non-essential element or device, of which the purpose is not exclusively that of clothing or protection, is forbidden. This shall also apply regarding any material or substance applied onto the skin or clothing and which is not itself an item of clothing. It is also prohibited to wear clothing or skinsuits to which non-essential elements have been added with a view to improving their aerodynamic properties such as, for example, "wings" under the arms or an extension between the helmet and the jersey or skinsuit. It is obligatory for clothing to follow the cyclist's body shape. No one, in any official capacity, is complaining about this. If there was something there, they would be. Italy would be screaming at the top of their lungs if this was in any way questionable. You'll also note in the linked article Alex Dowsett says "The UCI do all the checks. We spend 15-20 minutes with them before the start. They check the bikes before we come to the start as well. They look us up and down, and at the end of the day they let us roll down the start ramp or they don't." 1-2% is possible. If you believe it is anywhere near 7% then I've got some ocean front property in Montana you may be interested in. |

It did seem to me that your point was to ask if they were cheating, albeit among others. Perhaps the waffle here is over a Clintonesque nuance of what "accuse" means. However, I have no problem whatsoever with the accusation / question / discussion topic. It's a fair ask. The dance of regulation / innovative interpretation / clarification or change is as old as officiating. There's a lot of that going on here. And the lynch pin to some legitimacy, if not a full safe harbor, is the radio at the core of the purpose. It gives wiggle room that hydration or clothing doesn't. As for the "cleared it with officials" angle, there are various possibilities there. Certainly there could have been an advance consult. Another angle is to just present for the sign in and inspection. If passed, then silence is consent. There are a variety of infractions for which the officials may refuse a start if not remedied. This one seems to be pretty simple to remedy on the fly if the commissaire objected at the tech inspection. I have no idea what went down in this specific instance. |

It is absolutely inconsistent for rules meant to prevent hydration systems being used for aero benefit to not apply to race radios as well. Here is an unformatted copy/paste from the UCI Technical Regulations with some of the rules I'm referring to. I don't think you can read it and think that what they are doing with radios should be allowed.
Hydration is an essential physiological consideration for athletes during a physical effort. Neither bottles nor camelback systems should diverge from their original function.

It is mandatory for all riders who want to use a camelback system to present it to the commissaires before the start of the race at the risk of being disqualified. Items of clothing may not modify the morphology of the rider and any non-essential element or device, of which the purpose is not exclusively that of clothing or protection, is forbidden.

It is obligatory for clothing to follow the cyclist's body shape. Italy should be complaining. Due to the inconsistency I mentioned, it's stupid that such modification / placement of races radios is allowed. If it should be allowed, then open it up for hydration systems and other questionable clothing alterations as well. The range I mentioned was from an article that did actual testing with a 28oz bottle and some comments from an aero expert in another article. Whether you think it's possible or not doesn't matter, when actual testing demonstrates otherwise. I'm not claiming that Remco and Wout realized a 7% reduction in drag from the modified/strategically placed radios, but I don't think it's unreasonable to estimate that it could be in the range of 1-2%, based on testing that has been done on other riders. Sometimes small changes can produce seemingly disproportionate reductions in drag. It wasn't illegal. Hence, no protests from people actually involved. Wearing race radios in the front is fairly common, albeit not with the "padding" seen here. If this provided a huge advantage, every team would be doing it, or complaining about it. In short: not a big deal. |

Right. So why are there not explicit rules regarding race radios if they are being exploited in the same manner as hydration was?
Are there? No. Will there be? TBD. The beat goes on. So does the dance of "I'm not accusing anyone but look at these two violating what should be a rule." I already said it's a fair ask. If not an accusation. Whatever. |
