before purchasing: it must be between 17 and 20.5 mm.\u003cbr\u003e\n    • \u003cstrong\u003eNot compatible\u003c\/strong\u003e with Interphone CRAB, ARMOR, and MASTER line mounts, which use a

Installation is done by inserting the mount into the steering stem hole and tightening the locking screw.
