New crown of Ø16 mm in diameter and inverted carving.

This idea, the inverted carving of the standard, was created in 2008 as a novelty in the crowns of Z31 and Z32 teeth (old references SLPL 8031 and SLPL 8032) and that also included a small protuberance in the body of the crown. These old crowns have been replaced by the new ref. SP072431 and SP072432.

With this new measure of Ø16 mm. the crown/pinion gear can be adjusted more precisely using different thicknesses in the spacer and also can be use different pinion diameters.

Another great advantage of this new crown is in the total thickness of only 4.3 mm which gives more free space to adjust the wheel.

Sloting Plus is the first company in the Slot world to introduce, from the beginning, the M2.5 metric in all its crowns, wheels and extraible pinions due to its great tightening force and its longer duration of use.
