Extended Product Information
FAQs
Is this bolt compatible with all derailleurs?
No, this bolt is specifically designed for UDH (Universal Derailleur Hanger) systems and T-Type direct mount derailleurs. The T-Type version is not compatible with GX mechanical derailleurs.
What is the UDH system?
The UDH system refers to a specific derailleur hanger standard that consists of two parts: the hanger itself and a retention bolt. This system is designed for improved durability and shifting performance.
Can I use this bolt with any UDH hanger?
This bolt is designed to work with UDH systems, but it's best used with Hope's own Thru Axles for optimal integration. Ensure your frame is UDH-compatible.
How do I choose the right color?
The retention bolt is available in six of Hope's signature colors. Choose the color that best matches or complements your bike's existing components for a personalized look.
What torque setting should I use?
Always refer to the official Hope technical documentation or consult a professional bike mechanic for the precise torque specifications to avoid damaging components.
Where is this product made?
The Hope UDH Derailleur Retention Bolt is made in Barnoldswick, UK.
Does the UDH nut come with the bolt?
The product description refers to the 'UDH bolt' as the retention bolt. The 'UDH nut' is a separate component, and it's noted that the UDH nut is not compatible with GX mechs.
Troubleshooting
Derailleur feels loose or wobbly
Ensure the UDH Derailleur Retention Bolt is tightened to the manufacturer's recommended torque specifications. Check that the UDH hanger is correctly seated on the frame.
Shifting performance is poor or inconsistent
Verify that the correct retention bolt (UDH or T-Type) is used for your derailleur type. Ensure the bolt is properly tightened and that there is no damage to the derailleur hanger or the frame interface.
T-Type derailleur not mounting correctly
Confirm you are using the T-Type specific retention bolt. Ensure you are not attempting to use it with a GX mechanical derailleur, as it is incompatible.

Setup, Compatibility & Care
Setup: The Hope UDH Derailleur Retention Bolt is designed to replace the standard bolt that secures the derailleur hanger to the bike's dropout. Ensure your bike is equipped with a UDH-compatible frame and a compatible derailleur. The bolt should be installed following the manufacturer's torque specifications to ensure it is securely fastened without overtightening. It is recommended to use a torque wrench for accurate installation.
Compatibility: This retention bolt is compatible with Universal Derailleur Hanger (UDH) systems and T-Type direct mount derailleurs. Crucially, the T-Type specific bolt is *not* compatible with standard GX mechanical derailleurs.
Care: Clean the bolt periodically with a damp cloth to remove dirt and debris. Avoid using abrasive cleaners or solvents that could damage the finish. Periodically check the bolt for tightness, especially after demanding rides, and re-torque if necessary.
