I think Specialized helmets look far better than any other helmets. I just had to retire an M-series (I think) from a few years ago because of the suggestion that you replace after a few years of use. Really sad to see it go, since I loved the looks of it.

Now using an Echelon. Nice helmet. But, make sure you check out the internal web systems on them - some Specialized helmets have a turn wheel (nice because you can adjust with just one hand - I'll loosen mine on long climbs as a small way of easing the suffering) and some have the sliding two-hand system. Oh, and the S-Works helmets didn't work for me, though I like the looks, because my sunglass arms hit the webbing on the side. The glasses couldn't sit on my nose. I have seen some of the pros put their glass arms over the webbing (not the straps, the actual webbing) but I didn't like that feel.
