A twelve speed Deore XT chain, Quick Link included, with Hyperglide plus shaping for smoother shifts. Several rows in the listing look wrong, so go by the title and the speed rating.

Overview
A worn twelve speed drivetrain is where this Shimano Deore XT chain goes. It comes with a Quick Link at the full link count, and the maker highlights smooth, efficient shifting through its Hyperglide plus technology.
The XT chain is built to work with matching twelve speed Shimano parts, and the Quick Link makes fitting it simpler. The limitation is poor data quality: the item type row says lighting, the length row is in decimeters and the weight looks low, so trust only the title facts.
Who it's for
Mountain bikers who want a chain matched to Deore XT shifting. Anyone running another speed count, or a different brand drivetrain, should confirm compatibility first.
Pros and cons

- Single strand twelve speed design
- Item type row says lighting
- Weight and length rows look wrong

Performance notes
Shape of the plates and pins is tuned for smooth shifts across the cassette, which is the point of the Hyperglide plus tag. Pitch is a standard figure for bicycle chains and has to match the sprockets. A matching Quick Link means the chain can be opened and closed without special pins.
