If you read the article I cited, they conclude thatThanks guys, so is the Shimano dura-ace/xtr cn-hg901 my best option for an 11speed Shimano chain?
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.www.biketiresdirect.com
My gearing is: 1x11 Shimano Deore XT Derailleur with One-Way Clutch, Shimano Cassette 11-46 Tooth. This is a mountain bike.
"And Shimano users shouldn’t see much reason to stray, either. Shimano chains are seemingly the most efficient on the market while also offering decent durability. Yes, there are more durable chains which are almost as fast (such as YBN), but these may only be worth the extra expense if you’re in the chain waxing clan. If you’re sticking with Shimano 11-speed, I’d say it’s worth upgrading your Shimano chain to at least an Ultegra level, and if efficiency matters to you, then Dura-Ace is worth the extra."
Note that the efficiency edge on the Dura-Acece chain is only .5 watts. I think the Ultegra chain is the best bet in terms of durability, cost and efficiency, for your XT 11 speed, 11-46 set up which is the same as mine on both my CUbe trouing Hybrid and y Riese & Muller Delight Mountain.
