Steel Rear sprocket Ya 54Z Kr-843-54Z-428
Esjot is a German producer of the bicycle industry, with the most extensive range of chain wheels and sprockets in Germany. The steels used by Esjot meet the highest demands and thus meet OEM quality. The high tensile strength of this material guarantees a long service life. The materials Qste 420 and Qste 460 are always used for sprockets. Centre holes are machined on CNC automatic machines to a precise fit and fixing holes for screws are countersunk and cleanly deburred. Toothing in the Diamond-Cut results in best running properties and guarantees radial and axial runout tolerance of less than 0.2mm.
