On Sale New, Unused (Retail Price: 16,980 yen) Future Fin compatible carbon performance quad fins. Similar style to Machado quads. ◎ Material is a composite of carbon sheet and glass. Very lightweight, only about 319 grams for all 4 fins. Experience the outstanding flex of the carbon core. The foil shape is almost flat for all 4 fins. Delivers stable performance from small waves to large waves. ☆ Features Speed Performance Quad fins have less water resistance due to the absence of a center fin, making it easier to achieve straight-line speed. Especially excellent in acceleration during "ups" (the action of moving up and down the wave face). Freedom of Turns The tail section creates a loose (slippery) feel, allowing for smooth lateral movement and sharp turns and carves. Grip on the Wave Face The side fins grip the wave face firmly, enabling stable riding even on thick waves and steep sections. ◎ The color may be slightly different from the actual product due to the camera's resolution. Please understand. I have other items for sale. ◎ Sizes Twin Fin Height: Approximately 125mm Base: Approximately 141mm Box Height: Deep Rear Fin Height: Approximately 80mm Base: Approximately 105mm Box Height: Shallow ◎ There are two types of Future Fin box heights: deep (with an "f" mark on the box) and shallow (with an "x" mark). Returns, exchanges, and claims due to incorrect fin box height are not possible. Please check your board before purchasing. Thank you for your understanding. If fin removal is difficult, please adjust with sanding, etc. ☆ No accessories included. ◎ Although new and unused, there may be slight scratches or color unevenness due to the manufacturing process or storage. This is a great deal for those who don't mind. Thank you. #RobMachado #QuadFins #CarbonFins #future #CARBONQuad
