CORE SSF Replacement Line – Product Description

The CORE SSF Replacement Line is the official factory replacement for CORE’s Short Safety Frontline (SSF) system, used on modern Sensor control bars. This essential component ensures that your kite’s safety system functions exactly as intended, allowing the kite to flag out reliably and instantly when activated. If your current SSF line shows signs of wear, glazing, thinning, or fraying, replacing it with the genuine CORE SSF Replacement Line restores maximum safety, performance, and peace of mind on the water.

Built using CORE’s premium low-stretch, high-strength fibre, the CORE SSF Replacement Line is designed to withstand heavy loads, repeated flag-out cycles, and continuous saltwater exposure. Its protective coating minimises friction and ensures smooth movement during safety activation, preventing premature wear on the safety mechanism and bar components.

Replacing the SSF line regularly is vital for ensuring your bar remains safe and compliant with CORE’s factory standards. The genuine CORE SSF Replacement Line guarantees a perfect fit for Sensor 3, Sensor 3+, Sensor 4, and Sensor 4+ bar systems, making it a must-have maintenance item for riders who prioritise reliability and safety.
