FAQs
Are these bolts compatible with all Shimano cranksets?
No, these bolts and covers are specifically designed for the Shimano Dura Ace R9000 crankset only. Compatibility with other Shimano models is not guaranteed.
What is the material of these bolts and covers?
They are constructed from CNC machined Aluminium 6082 T6, which is known for its strength and light weight.
Do I need to use these with a specific type of chainring?
Yes, they are designed to provide a perfect aesthetic when mounting an external X110 chainring, and are compatible with Spécialités TA Ultra (SPG/SPH) hidden bolt chainrings.
How many bolts and covers are included in the pack?
The pack contains four chainring bolts and four corresponding covers.
Can I use these for single-chainring setups?
While they are designed for mounting an external X110 chainring, their application depends on the specific crankset and chainring configuration. They are intended for scenarios where the standard chainring bolt interface is used.
How do I ensure the color matches my crankset?
The product is designed to match your crank color. It's recommended to visually compare with your existing Dura Ace R9000 crankset before purchasing to ensure the desired aesthetic outcome.
What tools are required for installation?
Typically, an Allen key (hex wrench) of the appropriate size for the bolt heads is required, along with a torque wrench to ensure correct tightening to manufacturer specifications.
Troubleshooting
Bolts do not fit Shimano Dura Ace R9000 crankset.
Verify that your crankset is indeed a Dura Ace R9000 model, as these bolts are specifically engineered for it. Ensure you are not trying to fit them on a different Shimano or manufacturer's crankset.
Covers do not sit flush or fall off.
Confirm you are using the correct bolts and covers from the pack. Ensure the bolts are fully seated and tightened correctly, as this provides the base for the cover. Check that the chainring and crank interface are clean and free of debris.
Difficulty tightening bolts.
Ensure you are using the correct size Allen key or tool for the bolt heads. Check for any cross-threading or obstructions in the crankset threads. Do not force the bolts; seek professional assistance if needed.
Discoloration or finish damage.
Avoid harsh chemicals or abrasive cleaning materials. Clean only with a mild soap and water solution using a soft cloth. Ensure the product was compatible with any lubricants used during installation.
