As much as I don't like Specialized,
the fake helmets are not safe. They don't have the internal reinforcements or even the same foam for crash protection.
Many top end helmets require many more processes and handwork than basic ones. So, the knock offs skip those vital components and steps.
They are for the true posers that are too cheap to buy the real thing.
The sad thing is there are helmets in every price category that are safe and legit.
But the market is big for fakes.
