Flying Diamonds C J Nelson Involvement Single Fin 9.5" - Clear G10


Clear G10 Fibreglass


This fin is a classic. Drawing on the simple and proven designs of our forefathers, we added subtle elements to this design to optimize it for speed and added power through turns. Clean, simple lines and perfect mid-range flex. The function first concept makes this fin one of the easiest riding fins we’ve ever come across. Lots of control and drive in a beautiful package. A great choice for any single fin longboard.

CJ rides this fin in his involvement logs primarily but also rides it in his Parallax and Outlier models, and gliders when the waves get larger. This fin has less area and a touch more rake than our Power Flex model making it more maneuverable for small wave slashing.
