When I ride fix I always wear my helmet. And when i ride my mtb in the streets 98% of the time. Its probably a mental thing since I am not as comfortable riding fixed.
I have a Giro Havoc and it is huge on top of my head. Can anyone recommend a low profile helmet that wont look like you are wearing a bowl on your head. I tried the Atmos but i really dont want to spend $200 on another helmet
