I know it also receive accolades from Consumer Reports as having good impact protection and was rated a CR Best Buy. Online access to the reports is for subscribers only.
I
had a Bell Metro until I biffed it last Monday...ice, dark and bicycle wheels are a good combination

. It had several nice features like a light mount on the back of the helmet, a visor to keep the light from my helmet light out of my eyes, few vents for winter riding, a winter kit for blocking the holes and, most importantly, different sizes to fit my oversized melon. The Citi is a good helmet (Bell doesn't make the Metro anymore) but it only comes in 'universal sizes' which means it isn't large enough for those of us with larger heads (I think my head is large because of brains but others might argue that it just a thick skull

)
I did replace the Metro with a Specialized Tactic. At least it has a flatter rear than most helmets so I can still mount a light on the rear. I did get a Giro helmet liner for winterizing the helmet (slightly) but the helmet is still colder than the Metro.
If the Citi fits, it's a good helmet.
