Rainbow Fin Co at Rider Shack
Rainbow Fin Co makes some of the most respected handcrafted longboard fins available. Each fin is built with attention to flex, foil, and template — the three elements that determine how a longboard actually feels underfoot. We carry their full core range.
A-Flex series
The A-Flex is Rainbow Fin Co's signature series — a flex-tuned fiberglass construction that provides smooth, predictable flex through turns. Available in 7.75", 8.25", 8.75", and 9.25". Also available in Volan glass in 8.25" and 9.25" — Volan is a woven fiberglass that adds stiffness and a classic aesthetic.
Azul series
The Azul uses a colored resin layup that produces a distinctive translucent tint. Available in 6", 6.5", 7", 7.5", 8", 8.5", and 9" — the widest size range in the Rainbow Fin Co lineup. The Azul is a versatile everyday longboard fin.
MD3 series — Mikey DeTemple collaboration
The MD3 is a collaboration with Mikey DeTemple — one of the most distinctive stylists in modern longboarding. Available in 7", 9.5", and 10.5". The MD3 template is designed for nose-riding and classic longboard trim — a longer, more upright base with a raked tip.
Dog House series
The Dog House in 9.25" — a more performance-oriented template than the MD3. Designed for surfers who want more pivot and release from their single fin.
Fringe and Junod Flex
The RFC 8.75" Fringe — a limited colorway single fin. The RFC 9" Junod Flex — collaboration shape with a distinctly raked template.
Rusty collaboration
The Rainbow Fin Co. 6.25" Rusty Single Fin — a collaboration with Rusty Surfboards for smaller longboards and midlengths.
Fin hardware
Rainbow Fin Co also makes longboard fin hardware — the Longboard Screw Set and Longboard Fin Hex Screw Set for standard longboard fin boxes.
