FAQs

What size outer casing do these caps fit?

These caps are designed for outer casing with a 4 mm outer diameter.

Are these compatible with all brands of gear cables?

They are specifically designed for SHIMANO SP41/SP41 outer casing. While they may fit other 4mm casings, optimal performance is best guaranteed with compatible SHIMANO products.

How many caps are in a box?

Each box contains 100 sealed outer casing end caps.

What is the main purpose of these caps?

Their primary function is to prevent water and dirt from entering the gear outer casing, which helps prevent corrosion and ensures smooth shifting.

Can I use these on brake cable casings?

No, these caps are specifically designed for gear outer casing and may not be suitable or provide the correct seal for brake cable systems.

How do I install them?

Simply slide the cap onto the end of the gear outer casing to create a snug fit and seal.

Troubleshooting

Cap does not fit securely on the outer casing.

Verify that the outer casing diameter is 4 mm and that it is compatible with SP41/SP41 casing. Ensure no debris is obstructing the fit.

Shifting performance degrades despite using the caps.

While the caps protect the exterior, check the inner cable for wear or damage, and ensure the cable is properly lubricated and routed.

Cap appears to be cracked or damaged.

Replace the damaged cap immediately to restore the protective seal. Small cracks can allow contaminants to enter.

Setup, Compatibility & Care

Compatibility: These caps are designed for gear outer casing with a 4 mm outer diameter and are specifically suited for SHIMANO SP41/SP41 outer casing. Always verify your existing casing diameter and type before installation.

Setup:

  1. Cut your gear outer casing to the desired length.
  2. Slide one SHIMANO Outer Gear Casing Cap onto the end of the outer casing.
