                    Hyperglide (HG) series 10-speed compatible chain, recommended 
                    for Ultegra drivetrains. 
                     
                    • HG technology has chamfered inner plates to optimise 
                    shifting performance on HG sprockets. 
                     
                    • Durability is assured through a chromising treatment 
                    on link pins, and the heat treatment of rollers, pins, and 
                    plates. 
                     
                    • Mushrooming of the pins gives unsurpassed side-plate 
                    retention, enabling the chain to far exceed the BS/ISO standard 
                    for breaking force. 
                     
                    • 5.88 mm chain width, optimised for 10-speedSuperNarrow 
                    HG drivetrains. 
                     
                    • Zinc-alloy silver finish on outer plates, and grey 
                    finish on inner plates increase corrosion resistance.
