Complete Buying Guide for Road Bike Helmets For Large Heads
Essential Factors We Consider
When selecting a helmet for a larger head, the most critical factor is the adjustable dial system. Look for models that specifically mention “XL” sizing or a wide centimeter range. Additionally, prioritize MIPS technology if you want the highest level of rotational impact protection, as this is becoming the gold standard in helmet safety.
Budget Planning
You can find great safety-certified helmets for under $50, but adding features like MIPS or integrated LED lights typically pushes the price toward the $80-$150 range. Decide if those extra features are necessary for your riding style or if a high-quality, basic helmet will suffice for your needs.
Final Thoughts
Never settle for a helmet that feels like it’s squeezing your head. A properly fitted helmet is one you will actually enjoy wearing, which is the most important step in staying safe on the road. Take your measurements, check the brand’s specific size chart, and choose the one that offers the balance of features and comfort that fits your budget.
Frequently Asked Questions
Q: How do I measure my head for a bike helmet?
A: Use a soft measuring tape and wrap it around the widest part of your head, about an inch above your eyebrows. Keep the tape level and snug, and note the measurement in centimeters.
Q: Can I wear a smaller helmet if I remove the pads?
A: Absolutely not. Removing internal pads compromises the helmet’s safety structure and fit, which can lead to it sliding around during an impact. Always use a helmet that fits properly with the pads intact.
Q: Are XL helmets much heavier than standard sizes?
A: Generally, no. While they use slightly more material, modern manufacturing keeps the weight increase minimal so that they remain comfortable for long rides.
