Extended Product Information
FAQs
Is this chainring compatible with 12-speed drivetrains?
This chainring is optimized for 8, 9, 10, and 11-speed systems; performance with 12-speed systems may not be ideal due to chain width differences.
What is 104mm BCD?
104mm BCD stands for 104 millimeter Bolt Circle Diameter, which is the measurement between the centers of the chainring bolts on your crankset.
Does this include mounting bolts?
No, this product is for the chainring only. You should reuse your existing compatible chainring bolts.
Can I use this for a 1x drivetrain conversion?
Yes, this can work for 1x systems, though dedicated narrow-wide chainrings are often preferred for maximum chain retention.
How do I know if my crank is 104mm BCD?
You can measure the distance between two adjacent bolt holes center-to-center; for 104mm BCD, this distance is approximately 73.6mm.
Troubleshooting
Chain dropping or skipping during shifts
Check your chain wear using a chain checker tool and ensure your rear derailleur hanger is properly aligned.
Audible clicking or creaking under load
Verify that all chainring bolts are tightened to the correct torque specification and that the chainring is seated perfectly flush on the crank spider.
Pros and Cons
Pros
- Compatible with a wide range of drivetrain speeds (8-11 speed)
- Includes shift ramps for smoother gear changes
- Durable finish suitable for off-road conditions
- Standardized 104mm BCD ensures broad crankset compatibility
Cons
- Not compatible with direct-mount cranksets
- Requires specific BCD measurement to ensure fit
- Single ring size (32T) may not suit all terrain types
Setup, Compatibility & Care
To install, ensure your crankset is a 104mm BCD pattern. Using a standard T-25 or hex wrench, remove the existing chainring bolts, align the new Truvativ ring with the crank spider pins, and torque the bolts to the manufacturer's recommended specifications, typically between 8-10 Nm. To maintain the life of your chainring, keep the drivetrain clean from mud and grit using a bike-specific degreaser and apply a high-quality chain lubricant regularly. Periodically check that your chainring bolts are tight to prevent creaking or loosening during rides.
