Why Virginia Tech Helmet Ratings Matter

Understanding What the Virginia Tech Rating Means for the PIKIO Si

What Are Virginia Tech Helmet Ratings?

When shopping for a bicycle helmet, you will typically see certification labels such as CPSC in the United States or EN 1078 in Europe. These certifications establish minimum requirements that helmets must meet before they can be sold.

The Virginia Tech Helmet Lab developed an additional evaluation program that goes beyond these baseline certification standards. Their testing program rates helmets using a five star system based on laboratory impact testing.

According to Virginia Tech, helmets are tested at multiple impact locations and velocities. Sensors measure linear acceleration and rotational velocity, which are then used to estimate concussion risk in their testing scenario.

Virginia Tech explains that the results from each impact test are combined into an overall score, and a lower score corresponds to a lower estimated concussion risk in their evaluation system.

Why Certification Alone Does Not Show Differences Between Helmets

Certification standards are designed to ensure helmets meet a required minimum performance threshold. Once that threshold is met, the helmet passes the test.

However, certification testing does not rank helmets or show differences in performance between designs. As a result, two helmets in a store may both carry certification labels even though their impact test results may differ under other testing protocols.

Independent programs such as the Virginia Tech Helmet Ratings help provide additional information by comparing helmets tested under the same methodology.

Understanding the Virginia Tech Five Star System

The Virginia Tech Helmet Lab assigns helmets a rating from zero to five stars based on their test results.

According to Virginia Tech, the rating reflects the estimated concussion risk calculated from their laboratory impact tests. Helmets with lower scores receive higher star ratings.

This system allows riders to compare helmets evaluated using the same testing protocol.

The PIKIO Si and Virginia Tech Testing

The PIKIO Si cycling helmet was evaluated by the Virginia Tech Helmet Lab using their published testing methodology.

Based on those results, the PIKIO Si received a five star rating with the lowest score recorded among bicycle helmets tested by Virginia Tech at the time of evaluation.

As Virginia Tech explains, a lower score in their rating system corresponds to a lower estimated concussion risk within their laboratory testing scenario.

Engineering Inspiration Behind the PIKIO Si

During the development of the PIKIO Si, the engineering team explored biological structures that manage repeated impacts in nature.

One example that has been widely studied in engineering research is the woodpecker, a bird capable of striking wood at high speeds many times per day. Researchers have investigated how the bird's anatomy distributes forces generated during these impacts.

This concept helped inspire the development of the OBLIK™ modular liner architecture, which uses multiple interacting components within the helmet structure.

Engineering Approach

The PIKIO Si incorporates several structural features intended to influence how forces move through the helmet during an impact event. These include:

• Modular internal liner architecture
• Multiple foam densities within the liner structure
• Deep internal channels designed to support airflow
• Structural reinforcement layers integrated within the helmet

These elements work together within the helmet's overall architecture, which was developed through iterative design and testing.

Why Independent Helmet Testing Matters

Independent evaluation programs such as the Virginia Tech Helmet Ratings provide riders with additional information when comparing helmets.

By publishing their testing methods and results, Virginia Tech allows cyclists to review helmet performance within the context of their laboratory protocol.

For riders researching a new helmet, these results can be a helpful reference alongside certification standards, fit, ventilation, weight, and other design considerations.
