In cycling, where details and marginal gains are key, choosing a helmet is far from trivial. Nowadays, every team can choose between several models, not only for road and time trials, but also for the same specialty. And this is precisely the topic we explored with Edoardo Affini, representative of the Team Visma-Lease a Bike.
During the Tour of Italy, the Mantuan rouleur explained to us how he is using among his Giro helmets: the Aries Spherical and the Eclipse Spherical, two road models that at first glance may seem similar, but which in reality have very specific differences.
Let's go into detail with Affini. Meanwhile, if you want to "review" the technical characteristics of the two helmets, click here for the Giro Eclipse Spherical. And here for the Giro Aries Spherical.
Edoardo, you have these two road helmets at your disposal, the Eclipse and the Aries. How did you choose one over the other?
It's a choice that starts with the numbers. If we look at tests and scientific data, The Eclipse is the most aerodynamic, suitable for fast stages and sprints. The Aries, on the other hand, is more designed for mountain stages, for climbers.Let's put it that way. The main difference is ventilation: the Eclipse is more closed (14 vents, ed.), while the Aries is more open (24 vents, ed.), thus ensuring more ventilation. The weight difference, however, is not that significant (5 grams, ed.).
Is it also an aesthetic choice? Some people rely on their eyes for technical details...
No, not in my case. I choose based on functionality. In the first part of the Giro, I alternated them. When we aim for sprints with Olav Kooij, I tend to use the most aerodynamic one, the Eclipse. On days with more altitude or if it's hot, I wear the Aries for more ventilation.
Can you feel the difference in reaction much?
Honestly not. Even the Eclipse, compared to other aero helmets I've used, still has good ventilation. So yes, there is a difference, but it's not extreme.
And the fit?
Practically identical. The Aries might feel a little narrower, but not by much. But believe me, while running, you're focused on other things. Ultimately, there are differences between the two models, but these are laboratory-based; the human body doesn't notice them. I'm just saying random numbers: maybe you gain three watts for your helmet, two for your sock, four for your tire... In the end, you add up to 10 watts and you get that small advantage, which can make the difference between winning or losing a sprint or a time trial. But it's all very marginal.
Let's get back to the fit. Regarding adjustments and closure, are the two helmets identical?
Yes, they use the same system: rear adjustment with a wheel, different positions for the band that surrounds the head. You can adjust the height of the cap, moving it up or down depending on where it might bother you., depending on the type of glasses you have. This is very helpful. Furthermore, the MIPS system increases safety.
Looking back over the years, what's been the most comfortable helmet you've ever used?
Honestly, I'm very happy with these. One important thing is definitely weight: if you have an aerodynamic helmet but it's too heavy, it could bother some people's necks, especially on six-hour stages. And during a major Giro. Today, we always race at full speed, everyone's obsessed with aerodynamics. At the end of the day, when you take off your helmet, you might feel aches and pains here and there... and you go to the physiotherapist!
In a major Giro like this, do the details make the difference in the long run?
It's all very subjective. Some people are heavier and notice certain details less, while others are thinner and perhaps suffer more. As I said, the weight difference between the two helmets isn't huge. However, fit is important: being able to customize the adjustments is crucial for comfort, and during three weeks of racing, this is crucial.
When running, do you find yourself switching between intense and more relaxed phases?
No, I usually adjust everything before leaving and then I don't touch anything else. Also because the helmet must always be well fastened, otherwise it loses its function.
You mentioned weight. Moving away from the Aries vs. Eclipse comparison, what can you say about time trial helmets? Do you feel it more?
Keep in mind that our time trial helmet is visually large and bulky. However, it's much lighter and more comfortable than it appears. From the outside, it looks very heavy and uncomfortable, but once you put it on and find your position, it's very comfortable. Not only that, but The view is exceptional: very wide field of view, almost 220 degrees, without obstructions.
