Clarks derailleur cable end cap 4 mm CNC aluminum 100 pcs red

Clarks derailleur cable end cap 4 mm CNC aluminum 100 pcs red are CNC-machined aluminium end caps designed for use with bicycle derailleur and gear cables that require a 4 mm ferrule. Supplied as a bulk pack of 100 red pieces, these caps secure the exposed ends of brake and gear cables, reduce fraying of cable strands and provide a neat, corrosion-resistant finish. The CNC aluminium construction offers consistent dimensions and a lightweight solution for workshop assembly, maintenance and component replacement.

Advantages

The aluminium construction provides a balance of light weight and durability while the CNC machining ensures uniform size and smooth edges for reliable fitment. A 4 mm bore matches standard derailleur ferrule dimensions, and the bright red colour aids visibility during assembly and inventory management. Supplied in a quantity of 100, this pack suits workshop use and repeated servicing without frequent reordering.

Suitable for

• Securing the cut ends of bicycle derailleur and gear cables
• Bicycle assembly lines and repair workshops needing bulk consumables
• Maintenance and replacement of shifting systems on road, gravel and commuter bikes
• Applications where a 4 mm ferrule/end cap fit is required

Key specifications

• Material: CNC-machined aluminium
• Bore/internal diameter: 4 mm
• Quantity: 100 pieces per pack
• Colour: red
• Intended use: derailleur/gear cable end protection and termination

How to use

After cutting the cable to the required length, slide the Clarks aluminium end cap onto the cable tip and use pliers to crimp it gently until it is securely fixed. Ensure the cap fully covers the cable end to prevent strand unraveling. For housing terminations, seat the cap against the end of the cable housing or ferrule as appropriate. Inspect the crimped connection for a snug fit and re-crimp if necessary to avoid loosening during use.

Usage recommendations

Store the pack in a dry area to prevent surface corrosion and keep spare caps accessible during routine servicing. Use appropriate cable cutters and crimping pliers to achieve a clean cut and secure crimp, and replace any caps that show deformation or damage to maintain reliable cable termination.
