The Eclipse is finally here. No, not the latest astrological event which requires special glasses. We’re talking about Giro’s newest aero road helmet. Yes, that helmet . While we didn’t know what it would be called, we knew that Giro was working on a new model. And like most of their other top-end helmets recently , it uses their Spherical technology, powered by MIPS. For a helmet to be considered an ‘aero’ helmet, it has to be fast, right? As usual, Giro spent a lot of time in their in-house wind tunnel developing the Eclipse. That seems to have paid off. Thanks to the shape of the outers shell and how the airflow interacts with the ventilation system, Giro calls the Eclipse their fastest helmet yet (of course). In terms of actual numbers though, using the excellent Giro Aether as the baseline, the Eclipse is 163.5 seconds faster over 100 miles at 25mph. That means if you were wearing the Aether and covered 100 miles in 4 hours, you could have done it in the Eclipse in 3:57:16.5. For us mortals though, it’s probably more important that this speed didn’t come at the cost of all the ventilation. In fact, thanks to extensive use of their Therminator heat measuring head form, Giro was able to create an aero helmet that claims to be cooler than many non-aero competitors. To get anywhere close to the ventilation figures of the Aether is extremely impressive considering that helmet is more vent than […]
