Torsion Spring SD

(2 reviews) Write a Review

The new “SD” or, San Diego shortboard, is designed to be the ideal go-to shortboard for Southern California. The “SD” performs well in everything from the softer beachbreaks of Del Mar and Leucadia to the hollow reef breaks of La Jolla and Sunset Cliffs. Because of the versatility of the SD design it is the ideal one board quiver for a trip to anywhere on the East Coast. We took the predictable performance of the Yes, Thanks and dialed it in for smaller, softer surf by adding volume, a little width, and an increase in thickness. The rails of the SD are foiled with a low apex. A crowned deck helps maximize the volume in this fun shortboard. The bottom of the SD has a deep single concave that allows the board to generate speed through the flats. Ride the SD 2"-4" shorter than your traditional shortboard due to the additional volume, and enjoy the results of this looser, faster precision shortboard!

  • Perfect Replica

    Posted by Blue Spivey on Nov 19th 2019

    So I buckled my 5’10” SD Torsion Spring over the hurricane swells and asked Rusty to build another duplicate SD and it came out perfect. First sessions on it were this weekend in Florida and felt exactly the same no adjusting needed.
    Those program #s are there for reason. When you get a board you like and needs freshening up send in the program # and you’ll get pretty much exact same board.
    Thanks for all the support guys and as always couldn’t be happier with my equipment!

  • great high performance groveler

    I got a SD in Torsion Spring tech for small waves in beach breaks and I´m not disappointed. The board has a lot of glide through flat sessions and has a lot of speed, without sacrifice maneuverability and precision in the pocket. TS tech works well in bumpy waves and windy days too and I had a great time in waves up to 4 - 5´.
