FAQs
Will this fit my 105 or Ultegra crankset?
No, the FC-4700 chainring is specifically designed for the Tiagra 4700 crank series and is not compatible with other groupsets due to differing bolt circle diameters and aesthetic shapes.
Do I need to replace both chainrings at the same time?
While it is not strictly required, it is highly recommended to replace both the 48T and 34T rings if they show significant wear to ensure optimal shifting and prevent the chain from skipping.
What tools are required to install this chainring?
You will typically need a T30 Torx wrench to remove the chainring bolts that secure the rings to the crank spider.
Is this chainring compatible with 11-speed chains?
The Tiagra 4700 series is a 10-speed system; it is designed to work with Shimano 10-speed specific chains for the best performance.
What does the 'MK' designation mean?
The MK designation refers to the specific shifting ramp and pin configuration used by Shimano to match this 48T ring with the 34T inner ring for that specific crank model.
Troubleshooting
Poor front shifting performance after installation
Check the alignment of the front derailleur height and cage angle. A small adjustment is often needed when replacing chainrings.
Audible clicking or chain noise
Verify that all chainring bolts are tightened to the specified torque and that the chainring is properly seated on the crank spider.

Setup, Compatibility & Care
To install this chainring, you will need a set of T30 Torx wrenches and potentially a crank removal tool depending on your specific bike setup. Ensure the crankset is cleaned of old grease and grit before mounting the new ring. Align the index pin on the chainring behind the crank arm to ensure correct orientation. For long-term care, regularly clean your drivetrain with a degreaser and apply a high-quality bicycle chain lubricant. Periodically check the chainring bolts for proper torque as recommended in the official Shimano dealer manual to prevent creaking or loosening.
