Answer: To choose the correct size, measure your head circumference with a tape measure, placing it about 1-2 cm above your eyebrows and ears. Compare the result in centimeters with the size chart on the product page. Most of our helmets also have a smooth circumference adjustment system (a knob at the back), which allows for a perfect fit to your head.

Answer: Road helmets are typically lighter, more aerodynamic, and feature numerous vents that provide maximum airflow at higher speeds. MTB (mountain bike) helmets often have an extended rear for better protection and a detachable visor that shields the eyes from the sun, branches, and mud.

Answer: Yes. All ROCKBROS cycling helmets meet rigorous European safety standards (including CE certifications and relevant technical standards) and undergo stringent impact tests, effectively absorbing impact energy during a fall.

Answer: The helmet must be replaced after any significant impact or accident, even if no visible cracks are present on the shell (the internal structure may have been compromised). It is also recommended to replace the helmet every 3–5 years due to the natural aging of materials caused by UV radiation, sweat, and weather conditions.

Answer: The helmet should be cleaned exclusively with lukewarm water and a mild soap, using a soft sponge or cloth. Avoid using strong cleaning agents and solvents, as these can weaken the helmet's shell structure. After riding, it is advisable to allow the helmet to dry in a well-ventilated area, away from direct heat sources.
