What is the difference between the Evoline 2, and the Evoline 2 ST?
How can I know I got the ST version. I don't see anywhere on the helmet where it says ST and I don't see where the bluetooth batteries or speakers mount? Help.
The "ST" model is exactly the same as the "not ST" model in every way except that the ST model has pre-cut indentations in the foam core to place the elements of the Sharktooth bluetooth system. There is an indentation on each side for the ear speakers, and one in the back center for the battery pack.
These indentations are almost completely invisible on a simple visual inspection. You have to actually feel around for them with your fingers to tell the difference between the 2 helmet models.
I have also discovered that the pre-cut ear speaker locations are in the wrong places for my head shape, and I had to do a little creative engineering to remedy that problem. I posted a detailed analysis of this in the review section of the Sharktooth item. After having seen how much it took to get them located right for my ears, I would save the money and buy the non-ST model helmet next time... I'll have to do just as much work on that one as I did on my ST model, so why pay the extra $$?
