Product Description

The TK Flex is a classic fin that has been around for over 40 years that was originally designed as a single fin on smaller spoon boards. Today, at its smaller sizes it can be used as the center fin in a 2 + 1 setup – its flex will give you some serious snap on your turns. At its larger sizes you could demo it as a single center fin, too. That said, we recommend this fin for intermediate to advanced surfers who can tame its looseness.

The TK Flex fiberglass fin comes in 4 sizes from base to tip: 6.5", 7.5", 8.5" and 9.5", so you can customize it to your board and riding style. Each fin is handmade in California, so we cannot guarantee the colors of the fins available. For additional information on surfboard fins and fin setups, check out our Surfboard Fin learn section.

About Rainbow Fin Company: Rainbow was started back in 1968 in Santa Cruz, California, by a group of Santa Cruz surfers who were looking for fins to ride for their own boards and to sell to others in the surfing community. Since then, for over four decades and counting, and through the evolution of fin setups, designs and constructions, Rainbow has been relied on by surfers throughout the country and around the globe to provide them with the perfect fins for any conditions. Whether your go-to is a longboard or shortboard (or a SUP), a single, twin, thruster, quad, or five fin setup, or have FCS or Futures, Rainbow has you and your surfboards covered.
