Shimano 12v XTR / Dura-Ace chain - 138 links

Shimano XTR / Dura-Ace 12-speed chain 138 links

Shimano designed the XTR Dura-Ace CN-M9100 HG+ 138-link chain to improve its contact with the teeth of 12-speed chainrings. The narrow, slightly extended inner loops have been beveled to significantly reduce noise and vibration across the various gears. The chain runs centrally on the teeth of the chainrings and sprockets, which means it is much less exposed to friction, thereby improving performance. The SIL-TEC and chrome coating also contribute to the function and durability of the chain components.
