NiteRider Sentry Aero 260 Rear Light (Black)
NR-5088
Keeps guard night and day — an aerodynamic tail light with 260 degrees of visibility and 260 lumens of Daylight Visible Flash.
Overview
The Sentry Aero 260 pairs dual LED light strips with an aerodynamic shape to deliver 260 lumens of Daylight Visible red light across a full 260 degrees of visibility. An inner and outer lens design shapes the output for long-range visibility viewed directly from the rear, while still providing ample peripheral light — visible from nearly any angle. An extended profile, 2 diffusers, and an internal reflector work together for maximum side visibility.
Designed to fit both standard and aero seat posts via an interchangeable mount system (both strap types included), it's tested to FL1 Standards for lumen output and runtime, and carries an IP64 rating for dust and water resistance. At just 65g, it's genuinely lightweight for triathletes and road bikers alike. A full charge takes just 2:30 hours over USB.
