True Ames has been making high quality surfboard fins since 1979 and is a huge presence in the alternative surfboard world today. The Greenough 4-A has been the most popular single fin design for nearly 40 years. The full base combined with a tapered, moderately flexible tip provides solid drive off the bottom and sharp responsiveness through arcing turns. Designed for both speed generation and pocket surfing, the 4-A holds when you need it and releases when you need it. With increased flex from the Volan Cross, this fin will be a hit on a wide range of boards from mid-length to longboards.
