Troubleshooting

Stiff or sticky shifting

Check the cable housing for kinks or blockages. Ensure the inner wire is not frayed or damaged. Clean and re-route the cable if necessary.

Inconsistent gear changes

Verify the inner wire is correctly seated in the shifter and derailleur. Adjust derailleur limit screws and cable tension.

Cable fraying at the end

Ensure a clean cut was made with appropriate cable cutters. Use a ferrule to protect the end of the cable and housing.

Pros and Cons

Pros

  • Enhances shifting smoothness and precision.
  • Built for long-lasting durability in various cycling conditions.
  • Offers reliable performance for both road and mountain biking.
  • Provides a comfortable and dependable cycling experience.

Cons

  • Sold in bulk (box of 100), potentially excessive for individual users.
  • Requires proper installation and adjustment for optimal performance.
  • Steel construction may be heavier than some high-end alternative materials.

Setup, Compatibility & Care

Setup: These inner gear wires are designed to be installed as replacements for existing gear cables. Ensure your bicycle's shifter and derailleur are compatible with standard inner wire systems. Cut the cable to the appropriate length for your frame, install it through the shifter, housing, and connect it to the derailleur. Proper tensioning is crucial for accurate shifting.

Compatibility: Compatible with most standard road and mountain bike shifters and derailleurs that accept 1.2mm diameter inner gear cables. Always verify your component specifications before installation.

Care: To maintain optimal performance, regularly inspect the inner wire for signs of fraying or corrosion. Clean cable housing periodically to remove dirt and debris. Lubrication of the inner wire is generally not recommended for modern sealed systems, as it can attract dirt; instead, focus on keeping the housing clean and ensuring the wire moves freely.
