Gear Cable End Cap Clarks SP4 2163DP plastic with copper insert, pack of 50

Clarks SP4 2163DP gear cable end caps are plastic housings with an integrated copper insert, supplied in a pack of 50. These caps are designed to terminate and protect bicycle derailleur and gear cables, preventing fraying and securing the cable end where it enters housings, ferrules or anchor points. The combination of a durable plastic body and a metal insert provides dimensional stability and improves retention compared with simple plastic-only caps.

Advantages

The plastic body offers corrosion resistance and a clean external finish while the copper insert provides reliable compression and a secure fit on the cable strand. Supplied in a pack of 50, these caps are convenient for workshop use, fleet maintenance or assembly lines where multiple terminations are required. Their construction reduces the risk of cable slippage and maintains neat cable routing at the derailleur or shifter interface.

Suitable for

• Termination of bicycle derailleur and gear cables
• Routine maintenance and repair of mechanical gear systems
• Assembly of new bicycles or component upgrades
• Workshop and fleet servicing where multiple terminations are needed

Key specifications

• Material: plastic outer body with copper metal insert
• Pack quantity: 50 pieces
• Intended use: termination and protection of steel gear/cable strands
• Compatibility: standard bicycle derailleur and gear cables (mechanical systems)

How to use

Slide the cap onto the trimmed end of the gear cable so the copper insert aligns with the cable strands. Crimp the insert gently with an appropriate crimping tool or pliers to compress the metal onto the cable strands, ensuring the plastic body remains intact and seated. After crimping, check that the cable terminates cleanly and that the cap secures the end without excessive movement; trim any protruding strands before installation into housings or anchor points.

Usage recommendations

For reliable results, use a purpose-built cable crimper and ensure cable ends are neatly cut before fitting the cap. Do not over-crimp, as excessive force can deform the plastic body or damage the insert. Store unused caps in a dry environment to avoid contamination and inspect each terminated cable during the first ride or test to confirm secure seating.
