The contact-free, "upper-only" chain retention means the All-Mountain Guide will be virtually silent and completely drag-free when pedaling. The patented integrated skid will protect your crank and chainring and prevent the chain from ever contacting and potentially damaging your expensive frame.

• New nylon integrated skid protects chainrings and glides over rocks and obstacles
• Tracked and grooved upper guide / backplate interface increases stiffness and eases installation
• New co-molded "TR" upper guide with softer durometer interior for silent guidance
• All install and adjustment operations possible with just a single 4mm HEX wrench
