Since this is an old thread, I may give you some suggestions too that may help you folks in the future. Recently, I got my bike and I'm in the process of buying gears such as helmet, gloves, etc. Now, my friends are also got their bike and we're sharing thoughts on what brand of this and that to buy. I got my first ever
Giro Aeon Bicycle Helmet
I have to admit, I am not the most experienced rider but I am very particular about my gear. I do ride all day on the weekends and the helmet has to be one of the most critical investments a person can make. This helmet is lightweight, has excellent ventailation, looks slick, and extremely comfortable. Also with my head size 59cm, this puts me in the Medium size, as opposed to other Large sizes.
