6/7/8-Speed Universal Bicycle Chain with Pre-Installed Connector (116 Links)

Key Features

• Multi-Speed Precision Geometry: Specifically engineered to provide smooth, consistent shifting for 6, 7, and 8-speed drivetrains, featuring optimized plate spacing to prevent chain suck and dropped gears.
• Anti-Corrosive Nickel Plating: Treated with a specialized anti-rust finish that protects the steel core from oxidation caused by rain, mud, and road salt, ensuring a longer service life and reduced friction.
• Pre-Installed Connecting Link: Comes with a master link already attached or included, allowing for a fast, tool-free installation and easy removal for deep cleaning or drivetrain maintenance.
• Smooth-Shifting Inner Chamfers: The inner and outer plates feature beveled edges (chamfering) that help the chain "climb" and "drop" between cogs more efficiently, reducing drivetrain noise and shifting hesitation.
• High-Tensile Strength Pins: Utilizes reinforced chromoly steel pins with a specialized riveting process, providing the durability needed for high-torque climbing and urban commuting.

Replaces / Cross-Reference Part Numbers

• Shimano Standards: CN-HG40, CN-HG71, CN-HG50, CN-UG51.
• SRAM Standards: PC-830, PC-850, PC-870.
• KMC Equivalents: Z8.3, Z7, X8 series.
• Specifications: 1/2" x 3/32" (Standard width for 6-8 speed), 116 Links.

Compatibility & Fitment

This chain is a universal replacement for legacy and entry-level drivetrains across various cycling disciplines. Key compatible groupsets include:

• Shimano: Fits Tourney, Altus, Acera, and older Claris (8-speed) groupsets, as well as vintage 6-8 speed road and mountain bike systems.
• SRAM: Compatible with X3, X4, and legacy 3.0 series mountain and hybrid drivetrains.
• Campagnolo & SunRace: Works with vintage 8-speed Campagnolo and standard 6/7/8-speed SunRace cassettes and freewheels.
• Bike Types: Ideal for mountain bikes (MTB), road bikes, hybrids, gravel bikes, and cyclocross setups utilizing 18, 21, or 24-gear configurations.
• Note: This chain is not compatible with 9, 10, 11, or 12-speed systems, as those require a much narrower chain width.

When to Replace

• Chain Wear Reading: Use a chain checker tool; for 6-8 speed chains, replace once it reaches 0.75% wear to prevent the chain from prematurely wearing down your cassette and chainrings.
• "Ghost" Shifting: If the chain jumps between gears or slips while pedaling under load, the internal rollers and pins are likely worn beyond their tolerance.
• Visible Rust or Stiff Links: Excessive oxidation or links that no longer pivot freely through the rear derailleur pulleys indicate the chain is nearing the end of its life.
• High Mileage: Depending on riding conditions and maintenance, these chains typically last between 1,500 to 2,500 miles.
• Loud Drivetrain: A persistent "dry" or grinding sound that remains even after proper cleaning and lubrication.

Installation Tips

• Chain Sizing: Do not use all 116 links unless required. Compare the new chain to your old one or use the "Big-to-Big" method (wrap the chain around the largest front and rear cogs without the derailleur and add 2 links) to find the correct length.
• Clean Before Lube: **PRO TIP:** Wipe away the sticky factory packing grease with a clean rag before applying a high-quality, weather-appropriate bicycle lubricant for the best performance.
• Connector Orientation: Ensure the pre-installed master link is snapped fully into the "locked" position. You can do this by applying downward pressure on the pedal while holding the rear brake.
• Derailleur Routing: Pay close attention to the routing through the rear derailleur pulleys. Ensure the chain does not rub against the metal tabs or cages of the derailleur.
• Check for Stiff Links: After installation, back-pedal several times to ensure the chain moves smoothly through the entire drivetrain without catching.
