Colton Ricewrote a review of Lezyne Super Drive XL Headlight on October 20, 2015
Familiarity: I've put it through the wringer
Lezyne makes some great LOOKING product I will give them that. But quality of build and functionality have been lacking in any Lezyne product I have used and this is no exception.
This thing is full on metal meaning it is heavy. They made some overcomplicated mounting system involving a clamp and rubber shims. What the heck, just give it a rubber strap and call it good! The clamp does not stay on tapered bars well at all and will come loose, then say good by to the rubber shims that help it fit.
The crappy clamp system combined with the heavy weight means that after a bump you will almost always have to adjust the light back to wear you had it.
Thinking about using this mountain biking? FORGET IT
My other issues is that the usb port on the light to charge it is junk. You have to fuss with it's position in order for it to charge. I plugged in overnight to charge and was disappointed when it was still completely uncharged. A slight jostle of the charging wire made it start charging again.
So why the two stars? The beam is good and it looks nice.......
