General Specifications
About the Product
You're not on a bike to pose in front of the coffee shop. You're on a bike to ride. Rain and our - bad roads be damned. You're committed. Just like the Gage: Classics-born, pro-proven and every ounce a Bell. Featuring our two-way adjustable TAG fit system odor-eliminating X-Static padding and svelte rigging - lightweight webbing, buckle and cam-locks - so there's no excuses.
The Giro Aeon marks a new era in helmet design. Starting with a full roster of our best features, we optimized the design of every component in the helmet and even the shape of the helmet itself to reduce weight by 28% overall.

What customers say about "Features"
Bell Gage Stripes Bike Helmet
  • Feels great on my noggin, but Bells have always fit well.
  • Lightweight and good ventilation. Retention system feels great and new strap material is a nice change.
  • It is very lightweight. I ride in very hot weather now and it is no difference in comfort either with a helmet or without - the ventilation is very good indeed.
  • My head is 56 cm, and I bought S! It fits very well.
  • This helmet has a nice adjustable system on the back like most high-end helmets do. You can fine-tune your fit by adjusting the tightness around your head.
Giro Aeon Road Cycling Helmet
  • The ventilation is unreal on this helmet, at least in my experience.
  • Wearing it for a couple of rides I find the wind easily brushes over you head through the helmet's many generous gaps.
  • It was comfortable and it also felt cool to wear both literally and figuratively.
  • The RocLoc 5 system is a vast improvement over the older systems. It lets you micro dial-in the tension adjustments.
  • Hitting downhill speed at 45mph and tucked, I noticed the airflow channeling effectively.
