Bridging the gap between the CI Keel and AM Twin - this high area twin fin provides the drive and hold you expect from a keel, with the pivot and release found in the upright AM twin template.
$120.00
Overview
"A twin fin that you can push harder, turn tighter, and surf more vertically" - Britt Merrick
Placing it's self in the middle of the CI family, the BM template has a swept back long leading edge that leads into a full rounded tip. Different from other twin templates, this fin is designed to feel secure when laying into a longer turn or driving hard off the bottom.
With the CI Twin Pin/CI Mid in mind, the idea was to help anchor the tail to the wave face so surfers could take a more aggressive approach to riding a twin fin.
Board Types
Performance Glass
Performance Glass (PG) fins are machine cut from 30 layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
Large - Extra Large (One size suits all)

Very good fins for Lost RNF Retro
Perfect
Works well in my Lost MR California Twin!
They are great. You should get some.
Does what they said it would. Turned the black baron from a skatey seldom surfed board to a summer ripper. Perfect in the twin with a pin too.
