Ultra-Lightweight SeatPost Mimic Mount for Tailfin Cargo Systems

Secure Rear Lighting for Your Tailfin AeroPack, CargoPack & SpeedPack Tired of clip-on rear lights that shift during technical terrain or obstruct your bag straps? This 3D-printed adapter transforms any standard seatpost-mounted rear light (Lezyne, Cygolite, Garmin, etc.) into a secure, integrated lighting solution for your Tailfin cargo system. Why This Matters: Endurance cyclists and bikepacking adventurers need reliable rear visibility that doesn’t compromise cargo access or add unnecessary weight. This purpose-built mount integrates seamlessly with Tailfin infrastructure—no compromise on safety or function. Key Features: • Stability by Design — Mushroom-shaped base prevents sliding or rotation under vibration and shock • Dual-Layer Security — Built-in loop secures your light’s mounting strap as secondary retention • Featherweight — Minimal weight addition (9.1g PETG-CF, standard PETG comparable) for ultra-distance riding • Tool-Free Install — No new hardware; uses one existing M5 screw on your Tailfin system • Dual-Light Capable — Install two adapters (one at each attachment point) for redundant rear lighting on multi-day events Perfect For: • Ultra-distance gravel grinding and bikepacking expeditions • Multi-day events requiring backup lighting • Riders seeking lightweight, integrated solutions • Anyone frustrated with unstable clip-on lights on technical terrain Compatibility: • Works with Tailfin AeroPack, CargoPack, and SpeedPack systems • Compatible with any standard seatpost-mounted rear light (27.2mm interface) Engineered for Endurance: Designed by a 1,500km+ ultraendurance cyclist who understands real-world demands of multi-day bikepacking.
