The new Shimano XTR, XT, and SLX 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.

This design prevents premature ring and chain wear that can come from non-optimized tooth profiles.
