Ccm bike helmet? You are joking right?
I wear a hard hat and gas station sunny's.
if it can stop a brick from cracking my head open, it should be alright for smashing my face off the bars going 80mph?
80mph... what are you riding that you can crank out that speed?
myself I wear a kali avatar DH helmet. crazy light, and mass venting works awesome. most of the speeds we travel on mtn sleds, including trails, is 80km/hr tops ground speed
