Shimano CN-HG901-11 chain for XTR and Dura Ace - the version with master link

The Shimano CN-HG901-11 Quick-Link 11-speed chain is, unlike an earlier version, assembled with a master link. It has SIL-TEC coating on the outer plate, inner plate and roller, which provides extreme friction reduction, increased performance and better self-cleaning. Hollow pins also save weight. CN-HG901-11 chains are premium products for XTR and Dura Ace groupsets and can be used on E-bikes. Note the direction during installation.

Shimano's ultra-low friction surface treatment Superior to simple coating, SIL-TEC is an advanced plating process that improves system performance through the use of imbedded fluorine particles. SIL-TEC products run smoother and wear longer in all conditions.

The CN-HG901-11 chain has an asymmetrical design. The direction of travel must therefore be taken into account when installing. The specially shaped plates optimise the mesh between sprocket and results in smoother gear changes even under load. To save weight, these chains have recesses in the inner plates and hollow pins. The side with the mark is the outside.
