The BST-R is a patented design feature in which the design of the rim flange is based on the shape of the tyre bead. This ensures an ideal fit on the rim for the best possible tubeless sealing. In addition, the tyre can be expanded to its full volume. The result is more traction and less rolling resistance for increased speed.

Wideright
Perfect interaction – the full tyre volume without negatively affecting the tread shape or sidewall height. This creates an optimal position for maximum traction and minimum rolling resistance.
