Flex Rears

£24.50

Our original fin for performance wave riding and the first choice for pro team riders whether twin, quad or thruster. Great flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base.  Will loosen up a ‘stiff’ board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.

1 review for Flex Rears

  1. “I am 51, 87kg and very amateur, sailing on and off for 30 years, usually in side/onshore conditions. I tried the 17cm flex fins in my Mistral Twinser.
    I had the stock epoxy fins in 17cm , but tried the k4 flex fins in 17cm on a recommendation.
    They transformed the feeling of the board, from 3.8m through to 5.3m.
    It was smoother in the gybe, easier in standing chop and seemed to have a bit more grip when turning on the wave.
    They simply made sailing more relaxed and definitely improved my wave riding attempts.
    I had my straps forward, mastfoot middle and fins towards the back of the boxes.
    The fins are now in my Goya 94 and work well there.”
    With thanks Rob Castle.
