Slot Box Fin MX Evo 21cm Select SM027010121

Description:

The Slot Box Fin MX Evo 21cm from Select is a compact, high-performance fin engineered for explosive acceleration and reliable grip in planing conditions. Its super-stiff profile runs from the base to the tip, delivering direct power transfer for earlier take-off and confident rail hold when driving through turns. Built with a high-stiffness composite construction, the MX Evo balances durability with a lightweight feel to reduce drag and enhance responsiveness. The short, compact outline promotes quick pivoting and agile freestyle maneuvers while maintaining straight-line drive. Precision molding and a slot-box mounting design ensure a secure, low-profile fit to compatible boards. This fin is ideal for riders who want rapid planing and precise control in freestyle and freeride applications.
