Lightweight road bike helmet with extremely good cooling
The best aero road bike helmet in the peloton just got even better ventilated. The S-Works Evade 3 has been redesigned from the ground up to provide more cooling. This makes it the first choice for even more stages. Through countless computer simulations in computational fluid dynamics and extensive testing in their wind tunnel, Specialized's own wind tunnel, they were able to develop a "diffuser" that reduces drag and improves ventilation. The newly developed diffuser optimizes the aerodynamic properties due to higher air permeability, which leads to an increased air exchange of up to 10%.
The occipital base adjustment system optimizes comfort by allowing the fit of the helmet to be tailored to the individual head shape. In addition, the helmet angle can be changed for better compatibility with different goggles. The Tri-Fix belt system offers drivers additional comfort through individual adjustment options, revised, thinner belt band with a width of 10mm minimizes belt noise.
The ANGi-compatible, ultra-light Mindset fine-tuning system can also be adjusted in height, and has been redesigned for better grip and easier handling while riding. The ultra-light and extremely comfortable MIPS Air Node technology is integrated directly into the helmet padding. It consists of a smooth, low-friction layer that effectively dissipates rotational forces. Based on Specialized 's development work, MIPS has incorporated perforations into this layer to maximize breathability, performance, comfort and weight savings.
Technologies used
In this chapter we explain the technologies that the manufacturer uses in this product.
MIPS
The MIPS® safety system was developed to provide additional protection for helmets in numerous accidents. In certain impact situations, the MIPS system can reduce dangerous forces that might otherwise be transmitted to the helmet wearer's head.
1. Conventional helmets are designed and tested for a straight impact. In most cases, however, the impact is at an angle, which can cause rotational movements for the head.
2. This rotational movement can cause brain injury.
3. The low-friction shell is designed to help reduce rotational movement of the head in certain cases of angled impact.
Straight impact - oblique impact
The brain is typically more sensitive to rotational motion than linear motion because it has a shear strength similar to that of water or gel. When rotational movement causes different parts of the brain to move at different times, the tissues can be stretched, causing concussions or other brain injuries.
Rotational motion is a common cause of concussion and more serious brain injury from an oblique impact to the head. The MIPS system consists of a low-friction shell that is fixed inside the helmet. The low-friction shell is designed to slide slightly inside the helmet in the event of an accident, allowing forces to be directed away from the head. It is said to help reduce the risk of brain injuries.
Most conventional helmets are designed for a straight impact, but in most cases the impact is at an angle. The low-friction shell can reduce the rotational forces of an oblique impact.
Security system with the brain as a model
Unlike conventional helmets, which are primarily designed and tested for a straight impact, the low-friction shell of the MIPS system mimics the brain's own protection system against rotational movement. The cerebrospinal fluid is our natural defense system that allows the brain to move offset to the skull.
