The drive cable is the powerhouse of the Nimble system. It allows the print head to be so light and still manages to transmit all the power needed.
They should last a lifetime. But there can be all sorts of reasons why they sometimes break or you might simply want a different length.
The cable comes with the sleeve only. The sleeve clamps can be transferred.
Note: If this is a replacement for an older cable (with a black sleeve) this cable will fit in the old coupler at the stepper only if you drill out the hole on the coupler with a 3.5 mm drill.
