NSP J7 RTM Fin Suitable for:

Riders wanting to upgrade their NSP Elements, Protech, or E+ boards and those into SUP surf who want to get more performance from their Allrounder in Cocoflax or Elements construction, try the J series fins with a little more bite.

Best used in a variety of all-round surf conditions, riders whose style is back-foot heavy will benefit from the added bite, and their board will slide less and slash more with RTM fins.

A pair of J RTM fins work well in combination with the Wave 6 Centre Fin, in simple thruster setup on surfboards, while sup boards in the DC series, like the DC Surf Wide or the DC Surf X, respond well to bigger fins when the waves are powerful and you need that extra bite. Heavier surfers tend to favor bigger fins, so keep that in mind when you are looking to upgrade.

NSP J7 RTM Fin Sizes:

Available in three sizes;
J3 (112.5mm)
J5 (115mm)
J7 (120 mm)
