Packing 150 lumens of output into a seatpost-friendly package, the Strip Drive Rear places five high-output LED emitters behind our latest Wide Angle Optics for 270-degrees of impressive side visibility. With 11 output modes and a 30.5 hour max runtime, there's an option for every setting and ride length—day or night. A versatile mounting system attaches to aero or round seatposts and recharging is handled by an included micro-USB cable.
