The Micro Drive Rear is the perfect complement to its Front counterpart. In standard mode, it outputs an ultra-bright 30 Lumen red LED light. The Micro Drive Rear also features a high-visibility 70 lumen Daytime Flash mode. The light easily attaches to a wide range of round seatpost diameters via a snap-fit Composite Matrix mount, with a multi-position, silicon rubber strap for tool-less installation. The dedicated rear mount points upward to ensure light is directed straight back. It is available as a single rear LED or as 2 different front/rear pairs (Micro Drive Front/Rear or Macro Drive front / Micro Drive Rear).
