The Giro Helios Spherical is a road bike helmet with advanced technologies, making it perfect for adventurous and fast cyclists. This bike helmet is compact, lightweight and very comfortable to wear.
The Spherical technology offers optimal fall protection
With the addition of the Spherical technology, this road bike helmet has excellent fall protection. This technology is powered by MIPS and helps to direct impact forces away from the brain. With Spherical, MIPS is fitted between 2 layers of EPS foam. This system protects your brain against the rotational forces of a fall by allowing a small amount of movement between the helmet and the head. Thus, the impact of a fall is better absorbed.
15 vents for pleasant cooling power
The Giro Helios Spherical has 15 ventilation holes and deep internal channelling to allow a cooling airflow to enter and exit. The chance of an overheated head is therefore minimal with this helmet, which increases your cycling comfort.
Perfect custom fit
Of course, the Giro Helios Spherical must fit well and feel comfortable. With the Roc Loc 5 Air fit system, you can adjust this road helmet perfectly. A simple turn of the dial is all it takes to make a small improvement.
Padding absorbs sweat exceptionally well
This road bike helmet is equipped with antimicrobial Ionic+ padding, which ensures that the helmet absorbs sweat exceptionally well and that you will have few, if any, problems in this respect while cycling. In this way, the Giro Helios Spherical is even more comfortable to wear than ever before.

Expert staff, who take their time. That's what you want as a consumer
- Constant 18 September 2024
What I am particularly positive about is the way the employee guided me to the best bike helmet for me. No pressure, trying on everything. Even the helmets that were still packed. And the packaging showed a lower price than the barcode indicated. Naturally got it for the lowest price. TOP!
