Captain Fin 8.5" Alex Knost Classic Longboard Fin Poor QualityReview by Mark Mark
The Alex Knost fin is not straight. It has a very noticeable bend to one direction. I would not purchase any fins from captain fin company. I also had to sand it down just to get it in my fin box. It is frustrating but at least I know to shop elsewhere from now on. Lesson learned.
