MOOSE RACING 520 FB The 520 FB is Moose’s top-of-the- line chain, which is their strongest and most durable offering. DETAILS: FB stands for “Fine Blanking,” an incredibly precise manufacturing process that yields perfectly cut links. Tight tolerances make the plate, pin and bushing union accurate and strong. Due to the accuracy of the cuts and the use of stronger alloyed steel, the FB has Moose’s highest tensile- strength rating at nearly 8000 pounds. Special sealing rings are chemically treated to increase strength and reduce friction. The FB treatment allows the O-rings to be impregnated with grease. FB rings are stronger and more durable than X-rings and offer significantly less friction. TYPE: O-ring chain. WEIGHT: 4. 55 lb. RETAIL PRICE: $119.95.

RENTHAL R1 WORKS The R1 Works chain has shot- peened alloy steel side plates for high-tensile strength and maximum impact load resistance. Chamfered inner links reduce the chance of chain derailment. DETAILS: The R1 chain has extended bushings to reduce friction between the outer and inner link plates, maximizing power output. Chromized bearing pins have been used for excellent resistance to wear. The gold-color side plates help prevent corrosion. Average tensile strength is 7644 pounds. Includes a pair of rubber gloves for keeping hands clean during installation (this is the only chain brand in our guide to include gloves). TYPE: Non-O-ring chain. WEIGHT: 4.05 lb.
