When you're blasting down the trail, looking ahead at the line you're about to step through, the last thing you want to hear is a dreaded rattling chain that's trying, and failing, to keep up. Whether you're building up a brand new dream machine or replacing a chain that has seen better days, Shimano's CN-HG901 11-Speed chain represents the best you can get among Shimano's line, which is appropriate, as it's designed to be used with the brand's pro-level XTR and Dura-Ace drive trains.
Like its predecessors, the HG901 features a slight asymmetry to allow it pair perfectly with Shimano's 9000-series drivetrain for smooth gear shifts and excellent power transfer. With Shimano's groundbreaking SIL-TEC low friction treatment, this chain glides through the cogs with minimal friction, so you can focus on the smooth climb, rock-lined singletrack, or bike lane ahead with a chain you can depend on.
Sil-Tec is Shimano's new ultra-low friction surface treatment. Superior to simple coating, Sil-Tec is an advanced plating process that improves system performance through the smoother and wear longer in all conditions.
