Both versions of the CR7 rods, spinning and baitcasting, are built virtually identically. The blank, guides, handle, etc are the same between the two versions. The primary difference is in the layout of the rod as a spinning reel and baitcaster require different configurations.
So you’ll want to make sure you select the correct version to correspond with the reel you’re going to be using. If you’re using a spinning reel, make sure you get the Cadence CR7 spinning rod version. Same goes with the baitcaster.
