I have it in the hanging position on my drop bars. Like that because it doesn't interfere with my hand position on top of the bars. You need to make sure that the light is on really tight so it doesn't vibrate off the holder clamp. Just ordered another one because mine came off (I was on blacktop that was rough) hit the ground, separated at the connection to the battery pack. Got worse when a car didn't see it. Just ordered another one because it is that good a light.
As soon as you take it out of the box, you can tell that this front light has had some serious engineering behind it. The mount is secure. Switching between different modes is easy when riding. And the Strobe mode is perfect for riding at night, as you get enough lumens to see, and the pulsed flash makes you even more visible to those around you. On my last ride, I foolishly didn't secure the mount to the light properly and had it slip off and crash onto the pavement at 25 mph. It survived with only a few scuffs, thanks to the machined finish that is strong. I can't recommend this light enough! Paired with the Knog Blinder Mini Chippy rear light, you are in safe and reliable hands!
