The Lightest 12-Speed Chain Shimano Can Make
Designed for Shimano's XTR M9100 12-speed MTB groupset, the Dura-Ace R9200 12-speed road groupset, and the Ultegra R8100 12-speed road groupset, the M9100 chain provides enhanced chain retention thanks to an extended portion of the inner plate.
It is also remarkably light compared to other chains in its class, weighing in at only 242 grams for 126 links.
The new chain features quick-link assembly and SIL-TEC treatment for extended durability.

Reviews
Decided to purchase this chain instead of the usual XT level chain. There is definitely a difference in shifting and seemingly durability for the first 300 miles. We�ll wait and see how it holds up in the future. But I love Shimano products
I know there's not enough of a gain to use a Shimano Dura-Ace chain over even Ultegra, or a competitor, especially factoring in price, but man do they work well. They're always quiet, the quick link Shimano supplies gives a nice, firm click when it snaps together too, which I do like.
Make sure you notice they are in fact directional, there's a small paper in the box that tells you which way to go (writing faces outward on the chain plates). Does it make a difference? Who knows, but the plates are ramped to shift better under load and it does in fact do it, so I put it on the correct way of course.
The grease they use seems to come off easier too, if you're a wax person (I am). That initial soak in your degreaser of choice seems to do a really good job.
Main thing for me is noise level, and smoothness, and the chain delivers for me. I hate the loud chain noise on an otherwise quiet drivetrain.
Catch a sale and stock up.
Why bother with lower range chains when XTR offers the best qualities and lifespan? Bought a pair for each my road and XC bikes; thoroughly cleaned to remove all factory grease and immersed in wax. Repeat each couple hundred miles. If this works for 6k miles for competitive cyclists that put much more watts to the pedals than 99% of us, then should be just fine for same or more as well as reducing the total cost of running our bikes. Did I mention that alloy treatment on this work for crisp-instante gear shifts? Don't hesitate, go for it.
When Shimano started rolling out 12-speeds across their lines, it took quite a while before availability reached us end consumers for ongoing replacement. I've been using 6701/Ultegra chains as fantastic value/performance for more than a decade, was fine using an Ultegra chain for the first replacement on my new 12-speed, but very prefer the slightly lighter and smoother shifting of the Dura-Ace for that bike (equipped with Dura-Ace drive train).
I just replaced my Ultegra 8100 chain with 5,700 punishing miles I put on it since early February of 2023. I run a 12 speed Di2 and take incredible care of my chain and every component of the groupset. I counted and matched the number of links that were already on my BMC SLR01, which was 110, and cut the chain for the Quick-Links. I was amazed by how much stretch I had put on my previous chain when I compared the old and new side-by-side - only a few milimeters, but the new chain results in a tighter drive train and feels amazing with its crisp and silent shifting. Shimano chains are fantastic products, but like everything mechanical in this world, it can wear or stretch. I am so glad I went with this 9100 as a nice upgrade for my bike.
Dura Ace chains are excellent, and the 12 speed variety sets a new high bar. These things last forever and are silent when running. They last for ages and darn near forever when waxed. They are expensive compared to the other chains in Shimano's lineup, but when factoring in the additional life span you get out of the rest of your drivetrain, they are dirt cheap.
