FAQs
Is this bolt compatible with all bike frames?
No, this bolt is exclusively designed for frames that utilize the Universal Derailleur Hanger (UDH) standard.
Does this bolt come in other colors?
This specific model is finished in a smoke colorway to match other components in the Hope ecosystem.
What tools are required to install this bolt?
You typically require a standard hex key or a specific torque wrench bit to ensure proper installation.
Why is CNC machining important for this bolt?
CNC machining provides higher precision and strength compared to cast or stamped alternatives, ensuring the derailleur stays in alignment under load.
Can I reuse this bolt if I change my hanger?
Yes, provided the threads are not damaged and the new hanger remains part of the UDH standard.
Troubleshooting
Bolt feels loose after a ride
Verify the bolt was torqued to the correct specification during initial installation and check that the hanger is seated flush.
Difficult to thread during installation
Remove the bolt, clean the frame threads of debris or dried grease, and ensure the bolt is aligned straight to avoid cross-threading.

Setup, Compatibility & Care
Installation of the Hope UDH Retention Bolt is straightforward: simply thread the bolt into the UDH interface on your frame and tighten to the recommended torque specification (typically found on the frame or hanger documentation). Ensure the threads are clean and lightly greased before installation to prevent seizing. Periodically check the bolt for tightness after the first few rides, especially after significant impacts or bike transport, to maintain optimal shifting performance.
