When to Replace Your Bike Helmet

When to Replace Your Bike Helmet

Bike helmets don’t last forever. Even if you aren’t in a crash, your helmet becomes less protective over time, reducing its ability to keep you safe. 

That's because the helmet's outer shell and other materials are affected by a variety of factors (including exposure to the sun, temperature fluctuations, and wear and tear), which can degrade those materials or make them brittle, lessening their ability to absorb impacts. 

It’s no surprise that wearing a proper helmet is the most significant aspect of bike safety. There’s no more reliable way to prevent cyclists from experiencing head and brain injuries. A March 2023 report found that wearing the right bicycle helmet:

  • Reduces the risk of head injury by 48%
  • Reduces the risk of traumatic brain injury by 53%
  • Reduces the risk of fatal injury by 34%

Still, over 130,000 riders are injured every year in the US following bike crashes. An estimated four out of five cyclists don’t wear a helmet while riding, and an even higher percentage is unaware of their helmet’s lifespan. 

So, how do you know it’s time to replace your old helmet? Here are a few pointers:

  • Replace your helmet every three to five years, depending on helmet manufacturers’ guidelines. 
  • Always replace your helmet after a crash.
  • Buy a new one if you notice cracks or dents. 
  • If the straps or adjusters are worn out and the helmet no longer fits, it’s time to replace it. 

Read on for more warning signs that your helmet may be outdated, guidelines for finding the best bike helmet for you, and tips on how to achieve optimal helmet safety.

Signs Your Helmet Needs to Be Replaced

It might sound obvious, but you should replace your helmet immediately after a crash. Helmets are designed to sustain only one major impact, so even if you don’t see dents, cracks, or other signs of damage after an accident, the materials (like the foam that absorbs any impacts) are likely still affected.

Replace your helmet after a crash or if you notice visible signs of damage.

But there are other warning signs, too:

  • Is there visible damage to the outer shell or lining? Even small things like dropping the helmet may impair its structural integrity. 
  • Are there signs of wear and tear? Seemingly minor things like faded colors and loose padding may be signs that the helmet’s glue, resins, and foam have deteriorated. 
  • Is the helmet over five years old? Just like the produce in your refrigerator, bike helmets expire. They’re made of foam (often polystyrene) in a plastic shell, but over time the foam dries out and becomes brittle, making the helmet less protective. 

Guidelines for Replacing Your Helmet

It’s important to follow your helmet manufacturer’s recommendations as well as advice from the Consumer Product Safety Commission (CPSC). This is especially true since newer helmets take advantage of advanced technologies and materials that reduce what are known as rotational forces, which contribute to concussion risk.

Also consider exactly how you use and store your helmet: 

  • Do you ride a road bike, mountain bike, commuter bike, etc.? While there is some flexibility in terms of using a certain style helmet for various kinds of riding, helmets for specific cycling styles do have advantages. For example, mountain biking helmets typically protect a larger area of the head, while road biking helmets often have enhanced breathability and ventilation. 
  • How often do you ride? Every day? Once a week? If you ride more frequently, you may need to replace your helmet more often. 
  • Do you ride in sweltering heat or freezing cold? Extreme temperature fluctuations degrade the helmet's materials more quickly.
  • Do you store your helmet in the garage? In direct sunlight? In your home? Exposure to the sun's UV rays as well as extreme temperatures make the outer shell and foam lining more brittle and less protective. Ideally, you should store your helmet indoors, where it's safe from these elements. 

Safety First

Remember, wearing a helmet during a bicycle crash can lower the chance of serious head injury by about 60%. That percentage decreases, though, if you’re wearing an old or damaged helmet. Compressed foam, a cracked shell, or a poor fit (like chin straps or adjusters that don’t stay in place) greatly increase the risk of serious head injury. 

The risks of traumatic brain injury (TBI) are numerous and severe—from short-term impacts like loss of consciousness, headaches, and nausea to long-term impacts like memory loss, communication problems, behavioral changes, and worse—so this is one area where you don’t want to cut corners! Prioritize safety over cost and make sure you and your fellow cyclists are well-protected.

How to Choose a New Helmet

Bicycle helmets are more advanced, comfortable, and stylish than ever before. If your helmet no longer fits—or if you don’t like the look of it anymore—it’s time for an upgrade!

Bike Helmet Categories

First, you’ll want to consider what kind of helmet you need: road, mountain, recreational, or BMX/multi-sport (which can also be used for skateboarding). The distinctions between them are minor (extra protection, aerodynamics, ventilation, etc.), but they can help you get the most out of your ride. 

General Bike Helmet Size & Fit Guidelines

Next, you’ll want to ensure that the helmet fits properly. Here are six tips for getting a proper fit:

  1. When the chin strap is buckled, the helmet should be snug but comfortable. You shouldn’t be able to move it from side to side or up and down.
  2. The helmet should sit level on your head without tilting to the front or back.
  3. The bottom edge of the helmet should be one to two finger widths above your eyebrow.
  4. Your eyes should be able to see the edge of the helmet when looking upward.
  5. The straps of the helmet should be even and form a “Y” that comes together right at the bottom of your earlobe.
  6. The buckled chin strap should leave only enough room for a single finger to be inserted between the buckle and chin.

Bike Helmet Features

Last but definitely not least, pay attention to the special features your helmet offers. As helmet engineering advances, new technologies protect you better than ever before. 

Multi-Directional Impact Protection System (MIPS)

A good example is multi-dimensional impact protection system (MIPS) technology. This innovation has been scientifically proven to reduce rotational motion by absorbing and redirecting rotational energies transferred to the brain from angled impacts to the head. 

There's also the Specialized ANGi sensor, which will literally call for help if you’re in an accident. 

Other attractive helmet features include tail lights and Bluetooth communications systems on some models. 

Long story short, bike helmet technology is advancing faster than ever before. Stop into an ERIK’S bike shop to see the newest available features!
