Hydrus Replacement Fins (Set of 3)

These are the same 4.5" click-in fins that ship with the Axis and iSurf models, now sold separately. If you lost a fin or broke one, this is the replacement set. They're made from semi-rigid TPU rather than standard plastic. That material flexes enough to absorb impact without snapping, so the mounting tabs hold up better in rocky river conditions. They're stiff enough to track well on waves and hold speed when you pump, but not so rigid they'll damage your board if you catch a rock. Set of 3 fins, $35 4.5" semi-flexible click-in fins, secured with two grub screws for a solid hold Semi-rigid TPU construction, more resistant to tab breakage than standard plastic fins Fits all Hydrus shortboard fin boxes, plus Hala, Sol, and many other inflatable river boards Compatible with the Axis river paddleboard and Hydrus iSurfboard These are the stock fins included with the Axis and iSurf models
