(2) NEW 126L 12-speed Shimano XTR Chain, 126 Link, CN-M9100 HG+ Hyperglide plus link technology. $69ea for Both.
Beware of COUNTERFEIT XTR chains, they are epidemic online (EBAY, ALIEXPRESS and AMAZON) costing $45-$60. A genuine M9100 chain is minimum $100 plus tax at bike shops. This is the genuine hollow pin chain with reputation for long life and toughness. This is clear when sizing it, the pin is very hard to break with chain tool. I have them for $79ea, or $69ea for 2. I have NEVER broken one of these and have removed them after 5000 miles
(1) Used with low use from a parted out bike that used a 34 x 51T drivetrain, clean and strong. Genuine Shimano. Sized to 118 links, comes with quick link. $39
ALSO have used 10-51T Shimano XT Microspline Cassette, $49 used, $89 new.
