There are few things as disappointing as a broken chain on the trial but we'd wager that one could only up that disappointment when reaching into their tool kit to find that the only quick-link they've got on hand isn't compatible with their shiny-new 12-speed drivetrain. Don't leave yourself hiking down the trail for hours bummed out about a mechanical toss Shimano's XTR SM-CN910-12 Quick Link Set into your pocket tool kit or saddle bag and ride without worries of broken chains. This handy quick-link pairs with Shimano's CN-M9100 CN-M8100 and CN-M7100 chains.
