Product Information

Full details

The Giro Eclipse Pro Spherical Helmet is an elite-tier road cycling helmet designed for performance-focused cyclists who demand a balance of aerodynamic speed, lightweight construction, and advanced safety. Leveraging CFD-validated design and Spherical Technology powered by Mips, it offers significant drag reduction and superior impact protection; however, its specialized aerodynamic shape may limit ventilation compared to dedicated climbing-focused helmets.

FAQs

What is the difference between Mips and Spherical Technology?

Mips is a protective layer, while Spherical Technology is the advanced integration of that layer using a ball-and-socket design between two separate liners.

Is this helmet suitable for hot weather?

Yes, it features 15 vents and deep internal channeling, though it is optimized primarily for aerodynamics.

How do I determine my size?

Measure the circumference of your head just above the eyebrows to match with Giro's sizing charts.

Can I replace the internal pads?

Yes, replacement pads are available if the originals wear out from extended use.

Is the helmet compatible with glasses?

The helmet is designed to be compatible with most standard cycling eyewear, though fit may vary by brand.

How often should I replace the helmet?

Giro recommends replacing the helmet if it has been involved in a significant impact or every 3-5 years due to material degradation.

Troubleshooting

Helmet feels unstable during rides

Adjust the Roc Loc 5.5 dial to increase tension and ensure the vertical height adjustment of the cradle is set correctly to cradle the occipital bone.

Sweat dripping onto eyewear

Check that the DryCore sweat management channel is clear of debris and properly seated against the forehead.

Straps rubbing against ears

Adjust the strap sliders located just below the ears to ensure the junction point sits comfortably without putting pressure on the earlobe.

Pros and Cons

Pros

  • Proven 17% aerodynamic drag reduction
  • Industry-leading Mips Spherical protection
  • Excellent sweat management system
  • High strength-to-weight ratio
  • Highly adjustable fit system

Cons

  • Premium price point reflecting high-end materials
  • Design optimized for speed over maximum ventilation
  • May not fit all head shapes due to specific internal geometry

Setup, Compatibility & Care

To ensure optimal performance, start by loosening the `Roc Loc 5.5 Air` dial before placing the helmet on your head. Adjust the straps to form a V-shape under your ears, ensuring the buckle sits securely under the chin. The fit should be snug but comfortable, with no excessive movement when you turn your head. For care, clean the outer shell with a damp cloth and mild soap. The internal padding is removable and machine washable on a delicate cycle; allow the pads to air dry completely before reinstallation. Avoid exposing the helmet to extreme heat, such as inside a locked car during summer, as high temperatures can damage the protective EPS liner.
