06B chains have straight shaped link plates and use split bushings. The intermediate plate of the multiple strand 06B chain is a single plate, and the thickness is 1.6mm. The thickness of the intermediate plate of the multiple strand 08B chain is 1.25mm. Connecting links are "cotter" style for size 16B-3 SBR and all sizes above 20B SBR. Takes account of a 35% reduction of fatigue strength when a single pitch offset link is used.
