Upgrade your bike’s shifting performance with the Geometric Gear Inner Cable. Designed for smooth, precise gear changes, this inner cable features a low-friction Teflon coating and durable steel core. Available in multiple finishes (Teflon Red, Teflon Black, Diamond Teflon Gold) to match your bike build. Ideal for road, mountain, hybrid or folding bikes across Malaysia.
Specifications & Dimensions
-
Variants / Colours: Teflon Red, Teflon Black, Diamond Teflon Gold
-
Weight: 250 gm
-
Core material: Steel wire, high tensile strength, compatible with standard derailleur systems
-
Coating: Teflon (PTFE) low-friction coating to reduce cable drag inside housing
-
Length: (Not explicitly stated) — typically shift inner cables are around 1,800 mm (1.8 m) or suitable length to cut as needed
-
Diameter: Common gear cable inner diameters are ~1.1–1.2 mm (check compatibility with shifter / housing)
-
Compatibility: Works with Shimano, SRAM, and other standard mechanical 8–12 speed derailleurs (depending on matching compatibility)
-
Intended use: For derailleurs / gear shifting application — not for brakes
Key Features & Benefits
-
Teflon coating ensures smoother, more responsive shifting under load or in wet conditions.
-
Steel core provides durability and better resistance to stretching compared to cheaper cables.
-
The color variants allow visual distinction (for build aesthetics or maintenance).
-
Low friction means less force is needed to shift gears, improving rider feel and reducing fatigue.
Usage Instructions
-
Preparation
-
Ensure you have the correct housing length, ferrules, end caps and cutters.
-
Clean and inspect the derailleur, shifter, and housing path before installation.
-
-
Routing the Cable
-
Thread the inner cable through the derailleur and housing path, ensuring smooth entry points (no sharp bends).
-
Pull the cable taut and align with shifter and derailleur mounting points.
-
-
Securing & Cutting
-
After routing and tensioning through the derailleur clamp bolt, tighten clamp securely (as per torque spec).
-
Use proper cable cutters to trim to length, leaving ~5–10 mm extra.
-
Fit a cable end cap/crimp to prevent fraying of the cable end.
-
-
Adjustment
-
Use barrel adjusters on shifter or derailleur to fine-tune indexing (so that each shift is crisp).
-
After installation, run through all gear shifts to check for smooth performance and no binding.
-
-
Break-in Period
-
Ride gently for the first few rides; small stretching may occur. Recheck tension and adjustments.
-
Precautions & Safety Notes
-
Always use proper cable cutters and ferrules — frayed or damaged cable ends can cut housing or produce poor shifting.
-
Avoid routing the cable through excessively sharp bends — this increases friction and reduces responsiveness.
-
Periodically inspect cable for rust, kinks, wear or damage — replace if any are detected.
-
Use grease or light lubricant in housing (or use lined housing) to reduce friction over time.
-
After heavy use or rainfall, check for any grit or moisture ingress that may impair shifting.
-
Do not use inner cables designed for brakes — gear cables are thinner and not rated for braking forces.
-
When adjusting or trimming cables, ensure all bolts are tightened properly to avoid slippage or shifts losing adjustment.
