Front sprocket, rear sprocket and a precut chain make a convenient kit for the dealer or consumer. Sprockets are made of high-quality steel and have OEM gearing. Chain is Regina's high-performance Z-ring series with gold outer plates and Z44 sealing rings, which dramatically improves performance and wear life; includes rivet-type masterlinks. 520 conversion kits include all the above, but the rear sprocket is aluminum rather than steel, which in some applications reduces the chain + sprocket weight by as much as 2.5 lb.
