I'm returning the Bell Metro Commuter helmet to Nashbar, in case anyone's considering this helmet.
In short, I'm returning it in favor of the Bell Citi 05' which is less than half the price but still gets good reviews from Consumer Reports. Here's what you get for your extra $30 with the Metro:
--Lots of weight, to make your head teeter. When I was wearing this thing I did everything in my power not to raise my head.
--You will be remarkably free from having any pesky wind hitting your head.
--Concomitant with that your head will feel like you're wearing a ski hat.
--You will look like you're wearing a salad bowl. It's bulky.
On the (seemingly) plus side, you will get:
--A little plastic bar to attach your blinkie to. Wheeeee! I'm blinking! From my head!!!
(Two caveats: unless you have a tiny blinkie, this makes the weight problem of the helmet ridiculous. I was using the Cateye TL1000. Also, when the blinkie is on the back of your head, you can't see it! this means you have to take off the helmet to turn it to the right pattern, or memorize which pattern is where and press it blind and hope it's on. The third alternative, taking off the blinkie and putting it back on the back of the helmet, is difficult and takes more time than removing the whole helmet.)
I don't recommend this helmet. I didn't notice any difference in fit between the large Metro and the Citi, by the way. Save yourself some cash.
