The new Shimano XTR 12spd Hyperglide+ chain works differently than other products on the market so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology. * The new HG+ chain interacts with the chainring much differently than a traditional wide/narrow design. Wolf Tooth engineers spent the time to understand how the system works and design a new tooth profile that is optimized for this system. * Engineered proprietary tooth profile maintains the quiet and smooth performance of the HG+ drivetrain with legendary Wolf Tooth chain retention. * Prevents premature ring and chain wear that can come from non-optimized profiles. Compatibility * Shimano XTR M9100 series cranksets. * Compatible with Shimano 12-speed Hyperglide+ chains Recommendations If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
