Yow have released their third-generation of surfskate systems, YOW System V.4 S4 and YOW System V.4 S5 (From the outside they seem identical. But they perform differently.)
V.4 S4 uses a 4mm spring, with a lighter feel. It’s ideal for surfskaters seeking the sharpest carves and cut-backs they can find, or for surfskaters between 30kg and 50kg.
V.4 S5 makes use of a heavier, 5mm spring. It offers an authentic surfing feeling to surfskaters above 50kg.
