Xbility Dual-Rate Rear Spring

A dual-rate rear spring featuring two different spring stiffnesses in a single spring. The extra-soft section provides a softer initial response, while the medium section offers increased stiffness as the spring compresses further. This progressive spring design allows for a balance between initial suspension compliance and increased support under greater compression. A set of dual-rate rear springs featuring different combinations of spring stiffnesses. Each spring combines two rates in a single spring, allowing fine-tuning of the rear suspension response and handling characteristics.
