Features:

  • Futures Compatible
  • Highly refined epoxy construction for added durability, increased speed and performance

Epoxy fins vs polyester fins:

  • Epoxy fins are more reactive, meaning a faster response time
  • Epoxy has a load of approx. 1800/2000lb x square inch vs 500/600lb x square inch of the poly resin
  • At high speed the epoxy fin is more reactive because it's able to handle the extra load. When the fin flexes it comes back faster, giving you a stronger spring back
  • More durable after extensive use poly fins become softer and lose their flexibility properties, while epoxy has a much longer life
