FCSII compatible. Depth 6” Base 5.2” Foil: flat inner face.

The original retro twin template, intended to be used without a stabilizer for maximum drive and pivot.

These fins take you back to a time of revolutionizing the way surfers approached the wave, and how they maneuvered their boards. This famous twin template produces exceptional drive and speed.

Pro Glass fins are cut from slabs of solid fiberglass, providing reliable performance in the most demanding conditions. The minimal flex ensures immediate response and steadfast control especially in larger and more powerful surf conditions.

✅ Good Things About MR Twin Fins

🌀 1. Speed Generation

  • MR twin fins are designed for down-the-line speed.

  • Their relatively upright template (compared to keels) allows for quick acceleration and snappy direction changes.

🔄 2. Tighter Turning Radius

  • The upright rake and narrow base give you a more pivoty feel, letting you do tighter turns than more drawn-out keel fins.

  • Great for beach breaks or punchy waves where fast reactions matter.

🎯 3. Balance of Drive and Release

  • They strike a nice balance between hold and freedom.

  • Enough base and surface area to drive through turns, but still easy to release the tail when you want.

🔧 4. Great for Hybrid or Modern Twin Boards

  • MR fins are versatile — they work well in:

    • MR-style twin boards (like the Super Twin)

    • Modern hybrids (like the Lost RNF Retro or CI Twin Pin)

    • Small wave boards that need more spark and less drag than a thruster.

🌊 5. Ideal for Small to Medium Waves

  • Their design shines in everyday surf — waist to head-high.

  • Helps you get the most out of mushy or playful conditions.

🛠️ 6. High-Quality Construction

  • Made from Pro Glass, for dependable and predictable performance.

🎨 7. Style Meets Performance

  • Riding MR fins often brings a stylish, flowing feel to your surfing — especially rail-to-rail.

  • This design is all about functional style, and these fins reflect that perfectly.
