Riding in this morning I found myself wondering that, are there "British" versions of the Bell city helmets (the Citi and Metro)? These helmets were great because they have little accessory kits that include a mirror, rain cover, and air vent plugs for cold weather. My morning commute it primarily through downtown Oakland on one way streets, most of the time on the left side of the road. That makes my (ordinarily very handy) mirror almost worthless, unless I want to check out the parked cars.
When I got to work I noticed that the visor has a slot on the right side for a mirror, but that the one I have is left-sided only (which makes me wonder if there really are left-handed smoke shifters, no matter what the people at the Wolfeboro Trading Post said). Are there right-sided ones for people who use the other side of the street?
On a less-whimsical note I could see this being handy for international touring, especially if there is just a second wee little mirror to pick up.
