I switched to convex bar end mirrors a couple of years ago, many on
the market. As a year-round commuter, I kept breaking or losing my
helmet mounted mirrors.
This unit is easily adapted, with a bit of messing around, to USS
recumbent, however, with the mirror so far away from your eyes, the
convex style doesn't give you much in the way of detail; one reason
USS and trikes tend to use helmet mirrors.
Editorially, it is a myth that, when riding a recumbent, it is more
difficult to turn one's head to check the rear or side. The idea is that
the action tends to swing the bike dangerously. Tosh, just takes
practice. It is, however, a bit tedious so I think we use mirrors more
assertively than upright riders. Still, it's silly not to ride with a mirror,
don't you think? I can't ride anywhere without my mirrors anymore than
I could drive without mirrors.
