Hobie Mirage ST Fin with Pin and Ring, (Grey/Black)

Hobie Mirage ST Fin with Pin and Ring This is the Square Top Fin for Mirage Drive.  Called the ST Fin with Pin and ring part # 81193.  You need two of these for each MirageDrive.  Designed for increased speed.  These ST designs add more surface area creating extra thrust and speed as well as slower cadence for crusing.  The fin tension screw allows adjustment to achieve low end torque or top end speed to meet the desires of the pedaler.  St fins fit any Hobie Mirage Drive.  This fin is 12" long.  This is NOT the ST turbo fin. .  You can look at the number of shark teeth to verify you want this one.  We list the turbo st fin as a seperate item and is it 13 and 1/2 " long.
