Cable lubricant Clarks Pancerz przerzutki CLARK'S SP4 4 mm x 30 m blue (teflon)

Clarks Pancerz przerzutki CLARK'S SP4 4 mm x 30 m blue (teflon) is a teflon-treated cable liner for bicycle derailleur and control cables. The product is supplied as a 4 mm inner-diameter, 30 m long blue-treated cable housing intended for installation during maintenance or assembly of mechanical shifting and braking systems. The teflon treatment reduces internal friction, provides surface protection against wear and moisture penetration, and helps maintain consistent cable movement for smoother gear changes and responsive control.

Advantages

The teflon-treated inner surface lowers friction between the inner cable and housing, which reduces stiction and helps achieve more precise shifting and braking. The continuous 30 m length allows cutting to required lengths for multiple wheels or workshops, while the 4 mm diameter fits most common derailleur and brake cables. The treated housing offers resistance to wear and moisture, contributing to longer service intervals and more reliable cable performance in varying conditions.

Suitable for

• Replacement or upgrade of bicycle derailleur housings and control lines
• Workshop or home maintenance where custom cable lengths are prepared
• Assembly of mechanical gear and brake systems on road, gravel, and commuter bikes

Key specifications

• Inner diameter: 4 mm
• Length: 30 m
• Surface treatment: teflon (low-friction coating)
• Color: blue
• Compatibility: designed for standard mechanical derailleur and brake cables

How to use

Measure and cut the required length of the treated housing using a cable cutter designed for bicycle housings to ensure a clean end. Install ferrules where applicable and route the housing along the frame following original cable paths to avoid sharp bends. Insert a compatible inner cable, secure at the lever and drivetrain components, then adjust tension and indexing according to component manufacturer instructions. Test shifting and braking operation and trim or re-seat housing ends if necessary to eliminate excess play or binding.

Usage recommendations

For best results, use with compatible inner cables and proper ferrules; inspect cut ends to ensure they are clean and free of burrs. Periodically check cable condition and routing, and replace housing sections showing excessive wear or deformation. When installing on hydraulic systems, ensure the product is only used for mechanical control lines, not fluid-containing hoses.
