What are Asym and BST-A rims?
Asym or Asymmetric rims are rims designed with an offset to one side to allow for spoke bracing angles that create a more balanced tension and stronger wheel. Stan's BST-A or BST-Asymmetric rim design incorporates our original patented Bead Socket Technology (BST) design to the equation, providing the easiest tubeless set up on the market.
