The Shimano Dura Ace / XTR CN-HG901 11-Speed Chain features an asymmetric plate design and an ultra-low friction SIL-TEC surface treatment for higher performance and longer life. SIL-TEC plating on the links and rollers makes for a chain that runs quieter, lasts longer, and sheds mud better than normal zinc-nickel plating. Hollow pins on the HG901 increase lightness, but the chain is still strong enough to handle the high-torque of electric motors for use in e-bike applications. Claimed average weight is 246.5 g for 116 links.
