FAQs
Is this chainring compatible with 11-speed systems?
No, the Stronglight Dural 5083 is specifically engineered for 9 and 10-speed drivetrains.
Does this chainring include mounting bolts?
No, the package includes the chainring only. You should reuse your existing high-quality chainring bolts or purchase a new set if your current ones are damaged.
What does BCD stand for?
BCD stands for Bolt Circle Diameter, which is the diameter of the imaginary circle that passes through the centers of the chainring bolt holes.
Can I use this for mountain biking?
Yes, provided your mountain bike crankset utilizes a 5-bolt 130mm BCD spider configuration.
How do I determine if my crank is 130mm BCD?
Measure the distance between the centers of two adjacent chainring bolts. For a 130mm BCD, this distance is approximately 76.4mm.
Is the material prone to corrosion?
The 5083 aluminum alloy is highly resistant to corrosion, but regular cleaning is still recommended to maintain the finish and performance.
Troubleshooting
Chain skipping or ghost shifting
Verify that your chain is not overly stretched and that the derailleur limit screws are properly indexed for the new chainring.
Chainring bolts keep loosening
Apply a small amount of medium-strength blue thread-locking compound to the threads of the chainring bolts during installation.
Fitment is too loose on the spider
Check your crankset BCD specification. You may be attempting to mount a 130mm BCD ring onto a 110mm BCD spider.
Pros and Cons
Pros
- Durable 5083 aluminum construction
- Precise shifting performance for 9/10-speed systems
- Widely compatible with 5-bolt 130mm BCD cranks
- Excellent power transfer efficiency
Cons
- Limited to 130mm BCD configurations
- Not intended for 11 or 12-speed modern drivetrains
- Requires professional-grade tools for proper installation
Setup, Compatibility & Care
To install this chainring, you will need a standard set of chainring bolt tools and a hex key. Ensure that your existing crankset features a 5-bolt 130mm BCD pattern, as this component will not fit 110mm (compact) or 144mm (track) spiders. During installation, it is recommended to apply a light layer of grease to the bolt threads to prevent seizing. For maintenance, clean the ring regularly with a bio-degradable degreaser and a stiff-bristled brush to remove grit that accelerates wear on the teeth. Regularly inspect the chain for stretch, as a worn chain will significantly shorten the lifespan of your new aluminum chainring.
