Lazer Helium Race Cycling Helmets
 

What about the Lazer Helium Race Cycling Helmets?

According to my information compared to the standard fit systems the Lazer Rollsys is a fully integrated mechanism which surrounds the head completely. By turning a smooth thumb wheel - situated on the top of the helmet - the Rollsys permits accurate and progressive peripheral sizing adjustment. I know this much about this so, Please share your views about this .......
