Almost positieve the lowers are the same. The XR has the beefier straight-cut gears up top, while the XZ has the same upper as the X. Hope i'm not getting my X/XZ/XR mixed up!

Gears, XZ will have a little faster speed, but not as strong. There is only one set of gears for the top of XR, XZ has different ratios, XZ changes ratio in lower.
