XRAY have introduced new front progressive springs for their XB8. These springs are slightly progressive, but under more compression they change characteristics to become more linear. This gives an excellent feeling & feedback in all different track conditions.

See: XRAY

Marked with five dots and available as a pair, the springs are individually measured, controlled, inspected and matched to provide identical damping characteristics. During the selection process, each spring is compressed in several fine increments and the values recorded, and then each spring is matched with another spring of identical characteristics.
