High-performance pinion gear manufactured from special lightweight aircraft duraluminium to have lowest weight. The pinions are manufactured by XRAY on a specially modified precision gear machine, which has ultra-precise tolerances and assures unparalleled concentricity. After machining, the pinions have all their edges chamfered and then are run-in. The pinions are then specially treated to give them an even hardcoat so they stay absolute true for a long time.
