Derailleur Pancerz Clarks PRE LUBE SP4 with PTFE 5 mm x 30 m, carbon black

Clarks PRE LUBE SP4 derailleur cable housing features a PTFE (Teflon) inner lining and a 5 mm internal diameter supplied in a 30 m coil in carbon black. It is intended to guide and protect derailleur cables, reduce friction between cable and housing, and enable smoother gear changes. Supplied as a continuous length, the housing allows cutting to custom lengths for workshop repairs or new builds on road and urban bicycles.

Advantages

The PTFE lining reduces internal friction and limits cable wear, promoting consistent shifting performance over time. The 5 mm bore is compatible with standard derailleur cables, while the long 30 m coil provides enough material for multiple bikes or for producing tailored-length runs. The carbon black finish offers a neutral, workshop-friendly appearance and resists visible staining from grease and grime.

Suitable for

• Replacing or renewing derailleur housing on road bikes
• Creating custom-length housing runs for commuter and urban bicycles
• Workshop and professional bike-repair use where bulk lengths are required
• Maintenance tasks aimed at improving shifting smoothness and reducing cable drag

Key specifications

• Inner lining: PTFE (Teflon) to reduce friction
• Internal diameter: 5 mm
• Length: 30 meters (continuous coil)
• Color: carbon black

How to use

Measure the required routing length on the bicycle and cut the housing to size with a suitable cable housing cutter to ensure a clean, square end. Fit ferrules or end caps as appropriate for the frame and components being used. Insert the derailleur cable through the PTFE-lined housing, route according to the bike manufacturer’s layout, and adjust cable tension and indexing as usual. After installation, check for smooth cable movement and retension or trim as necessary.

Usage recommendations

Use a dedicated housing cutter for clean ends and fit compatible ferrules to protect the housing bore. For best performance, pair the housing with a matching low-friction inner cable and periodically inspect for kinks, corrosion or excessive wear; replace sections when performance degrades.
