Ok, so I will be getting my first ever mountain bike. I am very excited and can not wait to start on some local trails. My questions is about helmet selection. As I am new to the sport, I will be falling down, ALOT. I was thinking about getting a full face helmet. My main concern is people thinking I look like an idiot. The trails around my area are in no way black-diamond level. They can be technical, with lots of big rocks and steep descents. Any thoughts for the nube?
