Product Information
Full details
The Shimano 105 FC-R7000 39T chainring is an essential component for road cyclists using an 11-speed drivetrain who need to maintain crisp shifting and efficient power transfer. Designed specifically for the 53-39T crankset configuration, this genuine Shimano replacement ensures perfect compatibility with your existing 105-series hardware, though users should note that it is strictly intended for 11-speed systems and may not be compatible with older 10-speed or newer 12-speed setups.

FAQs
Will this fit an older 10-speed Shimano 105 crank?
No, this chainring is specifically engineered for the 11-speed FC-R7000 system and will not provide optimal shifting performance on older 10-speed drivetrains.
Does this include the crank bolts?
No, this product is the chainring only. You will need to reuse your existing FC-R7000 chainring bolts.
Can I use this with a 50-34T crankset?
No, the 39T ring is designed for the 53-39T tooth combination and the ramp/pin placement will not align correctly with a 50T outer ring.
Is this chainring made of aluminum?
Yes, it is constructed from high-quality, lightweight aluminum alloy to balance weight and durability.
How do I know if my chainring is worn out?
Look for teeth that appear pointed or 'hooked' rather than flat-topped, or if you experience frequent chain skip under power.
Troubleshooting
Excessive noise during shifting
Check that the chainring is mounted in the correct orientation and ensure the front derailleur is indexed properly for 11-speed movement.
Creaking sound under load
Remove the chainring bolts, clean the threads, apply a light layer of grease, and torque them back to manufacturer specifications.
Chain dropping between rings
Verify that you are using a compatible 11-speed chain and that the front derailleur limit screws are set correctly.
Pros and Cons
Pros
- Perfect factory-spec fitment for FC-R7000 cranks
- Maintains professional-grade shifting quality
- Durable materials provide long component life
- Easy installation for those with basic bike tools
Cons
- Not compatible with 12-speed or 10-speed drivetrains
- Requires specific 110mm BCD 4-bolt crank architecture
- Requires proper chainring bolt torque to prevent creaking
Setup, Compatibility & Care
To install this chainring, you will need a T30 Torx or standard chainring bolt tool, depending on your specific crank hardware. Ensure that the chainring is oriented correctly; the side with the mounting graphics typically faces outward. Always tighten the bolts in a star pattern to ensure even distribution of pressure. Compatibility is strictly limited to 11-speed setups using the 110mm BCD 4-bolt pattern. To extend the life of your chainring, clean it regularly with a degreaser and a soft brush to remove road grit that acts as an abrasive. Periodically check that your chainring bolts are tight to prevent unwanted creaking noise.
