Shimano's 10-speed Dura-Ace Chain delivers awesome shifting, reliability and durability. The links are asymmetrical for faster, lighter shifting, superior power transfer and a quieter drivetrain overall. Plus, there are hollow pins for lightness and there's a special connecting link for super-easy installation.
Features and Information
For optimum shifting and braking, Shimano 7900 Dura-Ace components are best as a system (they're not recommended for use with previous versions of Dura-Ace).
