Ianwrote a review of Giro Phase Helmet on July 28, 2012
I took my new Phase (made by Bell Sports according to a sticker : ) out to a local trail park for about an hour today. It was sunny with a little bit of wind. I did not really notice it during my ride, which was great. I have not smashed it into anything yet, so I can not comment on that.
My head is about 22.5 in around so I got the medium (55-59 cm). It came with the height adjustment maxed out (in the 3rd position) and I turned the Acu Dial to about 75% closed. It is a good fit.
I did not see a side on view, so I am posting one. Too bad I was the only one around to display it : )
