Serfas MR-1 Mirror
The Serfas MR-1 bar end mirror features an unbreakable 68mm diameter stainless steel lens and can be mounted above or below your grip.
The curved inward extension design is significantly less likely to get broken accidentally.
The mirror will fit on either the left or right side of the handlebars with an expanding wedge design that adapts to fit almost any handlebar.
This design will also fit road bike drop type handlebars.
