Fendo GS1 Groove System
Fendo GS1 Groove System
Fendo GS1 is the first groove-performance system built specifically for the scoring zone.
Dirty grooves reduce friction.
Reduced friction reduces spin.
Reduced spin reduces control.
Inside 150 yards, that difference matters.
The GS1 helps golfers protect the conditions that create spin and trust what happens when the ball lands.
Powered by Fendo’s patented dual-bristle Groove System, GS1 delivers deeper, more consistent groove cleaning than traditional tools. A one-touch hydration mist loosens debris instantly, while the removable precision groove pick clears stubborn buildup when grooves need extra attention.
Built for everyday use, the GS1 features a custom soft-feel TPE grip and a removable sleeve system that allows golfers to personalize their setup while maintaining consistent performance.
Because clean grooves create friction.
Friction creates spin.
Spin creates control.
And inside 150, control decides everything.
