Seka ExAero MAG Bottles - Pair Magnetic - Black

The SEKA ExAero MAG Aero Bottle System combines aerodynamic efficiency with the convenience of a magnetic bottle retention system, offering a refined hydration solution for road, gravel and performance-oriented cyclists.

Developed around Fidlock's magnetic mounting technology, the ExAero MAG securely locks the bottle into place while allowing quick, intuitive removal with a simple twisting motion. The result is a bottle system that remains stable over rough roads, eliminates rattling, and provides fast access during high-intensity riding.

Unlike conventional round bottles and cages, the ExAero MAG features an aerodynamically optimized profile designed to smooth airflow around the bicycle. According to SEKA's aerodynamic testing, the system can reduce drag by up to 6.5–6.9 watts compared to traditional bottle and cage combinations, helping improve overall efficiency without compromising hydration accessibility.

Compatible with any bicycle using standard bottle cage mounting points, the ExAero MAG is equally suited to road, gravel and triathlon bikes, making it an excellent upgrade for riders looking to combine aerodynamic performance with everyday practicality.
