Product Information

Full details

The Giro Eclipse Pro Spherical Helmet is engineered for competitive road cyclists and enthusiasts seeking a fusion of aerodynamic performance, advanced impact protection, and sustained comfort. By leveraging CFD analysis and wind tunnel testing, this helmet provides a significant drag reduction, making it ideal for those focused on speed; however, its specialized aerodynamic profile may feel slightly more restrictive in ventilation compared to traditional, non-aero climbing helmets.

FAQs

What is Mips Spherical technology?

It is an evolution of Mips that uses a ball-and-socket design to redirect impact energy, allowing the outer shell to rotate independently from the inner foam liner during a crash.

Can I replace the internal pads?

Yes, the interior pads are removable and washable, which helps maintain hygiene and comfort over long-term use.

Is this helmet suitable for mountain biking?

While it is a road-specific helmet, it can technically be worn off-road; however, it lacks the extended rear coverage and visor found on dedicated trail helmets.

How do I determine if I need a Medium or Large?

Measure your head circumference at the widest point above your eyebrows and compare it to the Giro size chart, as fit can vary slightly between models.

Does the aero design make it heavier?

No, the Eclipse Pro utilizes dual-density foam to keep the construction ultra-light while maintaining high safety standards.

Troubleshooting

Helmet feels unstable or shifts during rides

Adjust the Roc Loc 5.5 vertical position and tension dial until the fit is snug against the occipital bone.

Sweat dripping into eyes during intense efforts

Ensure the DryCore brow pad is clean and properly seated against the forehead to maximize its wicking capability.

Straps rubbing against ears

Adjust the tri-glides on the side straps to reposition the intersection point until it clears the ears comfortably.

Pros and Cons

Pros

  • Proven 17% aerodynamic advantage
  • Industry-leading Mips Spherical protection
  • Highly effective sweat management system
  • Lightweight dual-density foam construction
  • Precision one-handed fit adjustment

Cons

  • Less airflow than non-aero climbing helmets
  • Premium price point reflecting advanced tech
  • Specific shape may not fit all head geometries

Setup, Compatibility & Care

To ensure maximum safety and comfort, start by placing the helmet level on your head, not tilted back or forward. Use the `Roc Loc 5.5 Air` dial at the back to tension the fit until it feels secure but not constricting. Adjust the side straps so they form a V-shape just below your ears, and ensure the chin strap has enough room for two fingers between the strap and your chin. To clean the helmet, use only mild soap, water, and a soft cloth; avoid harsh chemicals or solvents that could damage the outer shell or foam liner. Always store the helmet in a cool, dry place away from direct sunlight when not in use.
