The Lezyne Femto Drive Rear complements its Front counterpart perfectly, delivering excellent visibility with a 7 lumen output from its single red LED. It features an integrated lens switch made of high-grade optical material, which serves as an activation button that cycles through four Flash modes and one Solid mode. The CNC –machined aluminum body is lightweight, durable, and extremely weather-resistant. The Composite Matrix back cap features the Clip-On System for versatile strapped or clipped mounting. The multi-position silicon rubber strap attaches directly to the back plate to secure the light to a wide range of seat post diameters. The Side Visibility lens extends beyond the body providing 180 degrees of visibility, and increasing user safety. The back cap can easily be unscrewed to replace the two CR2032 disposable batteries. • Bright 7 Lumens
