FAQs
Does this wire come with end caps?
No, this product is the inner wire only. You will need separate crimp-on wire end covers for installation.
Can I use this for my road bike?
This wire is specifically designed for MTB and Hybrid bikes. Road bike brake and gear systems may have different cable specifications and tolerances.
How do I know if this wire is compatible with my components?
If your current gear or brake system uses standard inner cables that attach with a crimp-on end cover, this Clarks wire should be compatible. It is designed to fit all cycle component manufacturers' systems that use this standard.
What does 'pre-lubricated' mean for this wire?
It means the wire has a lubricant applied to its surface from the factory. This helps reduce friction as it passes through the cable housing, leading to smoother operation immediately upon installation.
How often should I lubricate this wire?
The wire is designed to be maintenance-free due to its pre-lubrication. However, for optimal performance, especially in harsh conditions, periodic visual checks for wear or contamination are advisable. Re-lubrication is typically not required unless damage occurs.
What is the difference between a brake inner wire and a gear inner wire?
While they often use the same materials and dimensions, brake inner wires are typically thicker and designed to handle greater tension for braking force, whereas gear inner wires are finer to allow for precise shifting actuation.
Can I cut this wire to any length?
Yes, you can cut the wire to your desired length. It is recommended to measure carefully against your existing cable or plan your routing to ensure an optimal fit without excessive slack or strain.
Troubleshooting
Stiff or sticky gear shifting
Ensure the inner wire is routed smoothly through the housing without any sharp bends. Check that the cable end is securely seated in the derailleur. If the issue persists, the housing might be contaminated and could require cleaning or replacement.
Brake lever feels spongy or has poor return
Verify that the brake cable is properly tensioned and that the end cover is firmly crimped. Inspect the brake calipers or posts for any obstruction. Ensure the brake housing is not kinked or damaged.
Wire frays at the end
Ensure a proper crimp-on wire end cover is used and securely attached. If fraying occurs frequently, the wire may be repeatedly subjected to excessive force or sharp angles during use or installation.
Wire is too short for installation
This specific wire is 2100mm. For longer applications, consider a longer specific-purpose cable. Ensure you are routing the cable with efficient curves rather than tight bends.
Pros and Cons
Pros
- Pre-lubricated for immediate smooth performance.
- Universal compatibility with major component brands.
- Low maintenance requirements.
- Sufficient length for most common bicycle setups.
- Durable and suitable for varied cycling conditions.
Cons
- Requires crimp-on wire end covers (not included).
- Pre-lubrication may wear over time, requiring occasional checks.
- Specific length might be too long or short for custom builds.
- Not designed for road bike brake/shift systems which may have different requirements.
Setup, Compatibility & Care
Setup:
- Ensure your existing cable stops and housings are clean and in good condition.
- Measure and cut the Clarks inner wire to the required length, usually slightly longer than the original cable to allow for clean routing.
- Slide the wire through the appropriate shifter or brake lever.
- Thread the wire through the bike's cable housing and frame stops.
- Attach a crimp-on wire end cover to the end of the wire to prevent fraying and ensure secure seating in the derailleur or brake caliper.
- Adjust your gears or brakes according to manufacturer specifications.
Compatibility:
- Brake Systems: Compatible with most standard mechanical disc brakes, V-brakes, and cantilever brakes that use inner brake cables with crimp-on end covers.
- Gear Systems: Compatible with most mountain bike (MTB) and hybrid bike gear shifters and derailleurs that use standard inner gear cables with crimp-on end covers.
- Not Recommended For: Road bike brake systems or electronic shifting systems.
Care:
While designed to be maintenance-free, periodic inspection is recommended. Check for any signs of fraying or damage to the wire. Keep cable housings clean and lubricated if necessary, although the wire itself is pre-lubricated. Avoid bending the wire sharply during installation to maintain its smooth operation.
