Doubletake offers three mirror options. The Enduro and the Adventure mirrors use DOT spec glass, and RAM components to position as needed. The Trail mirror is not DOT and remains stationary in position. If you want the mirror to be extended most of the time, we recommend the Adventure for stability and the larger glass size. If you plan to fold the mirror away often, but still ride on the road, we recommend the Enduro option. If you are looking for a low profile way to keep track of people offroad, the Trail mirror is for you.
