Like the PC-991, the PC-971 features inner and outer plate designs that offer faster and more accurate shifting at a more affordable price point. The PC-971 uses nickel-plated outer and gray inner plates. As with all Power Chain (version 2), we made some minor changes to further enhance our shifting performance with Truvativ Chainrings.

Features:

• Nickel plated outer and gray inner plates
• Power Chain re-designed
• Truvativ chainrings
• Powerlink is supplied
