This gear knob is very beautiful, well in hand ... too well !! consisting of a sleeve that slips over the shaft of the lever (3 diameters available) and the pommel I stuck the sleeve over the lever shaft with resin (only solution to securely join the two parts) and the knob is screwed on the sleeve .. all is well until the head rest in your hand, the diameter of the screw head is larger than the diameter of the thread of the sleeve !! so it takes out the resin and PASTE the knob on the sleeve From the lovely fair ganivelle
