Product Information
Full details
The Shimano Inner Gear Cable is designed for cyclists of all levels who require consistent, reliable shifting performance across road and mountain bike drivetrains. Crafted from high-quality stainless steel, this cable minimizes friction and resists corrosion to ensure smooth gear changes over extended use. While it offers excellent durability and universal compatibility for front and rear derailleurs, users should note that the kit includes only the inner wire, necessitating the separate purchase of housing and end caps for a full system replacement.

FAQs
Does this include the outer gear housing?
No, this is a single inner cable unit only.
Can I use this for my brakes?
No, gear cables have a different head shape and diameter compared to brake cables. Using the wrong type is dangerous.
Is this cable compatible with road and mountain bikes?
Yes, it is designed for universal use with both road and mountain bike shifting systems.
How do I prevent the end of the cable from fraying?
Once the cable is installed and trimmed, crimp a cable end cap onto the tip to keep the strands together.
Can I reuse this cable if I remove it?
It is generally not recommended to reuse a cable once it has been clamped by a bolt, as the wire strands will have been deformed.
What tools do I need to install this?
You will need a set of hex keys for the anchor bolts and high-quality cable cutters for trimming the wire.
Troubleshooting
Shifting feels stiff or heavy
Check the housing for sharp bends or internal contamination; apply a light bicycle-specific lubricant.
Cable is fraying at the anchor bolt
Replace the cable immediately and ensure the anchor bolt is not over-tightened, which can crush the wire strands.
Difficulty threading through the housing
Ensure the end of the cable is cut cleanly with sharp cutters and not frayed.

Setup, Compatibility & Care
To install, first remove your old cable by shifting into the smallest cog. Use a professional-grade cable cutter to trim the new wire to your specific length—avoid using side cutters, as these will fray the ends. Always ensure the cable is seated correctly in the shifter mechanism.
Compatibility Note: This cable is designed for Shimano-standard indexing and works perfectly with SP41 housing. For best results, lubricate the cable lightly with a Teflon-based grease before insertion. To maintain the system, inspect the cable housing every season for dirt buildup, and replace the inner cable if you notice any visible fraying at the anchor bolt.
