If you're trying to decide between DoubleTake's Enduro Mirror or their new Adventure mirror, our advice is simple...
Choose the Enduro Mirror if you plan to fold the mirror down a large percentage of the time, or if you do a lot of off-road riding, These mirrors easily tuck away right behind the headlight, and are more suited for off-road riding.
Choose the Adventure Mirror if you plan to leave the mirror extended most of the time, or if you do mostly highway or street riding. The more compact design of this mirror is more stable at highway speeds.
Both mirrors provide outstanding visibility, are virtually indestructible, are easy to fold/remove, and will help protect your controls in the event of a crash.
