Product Information
Full details
The Burgtec UDH Hanger is an essential component for mountain bikers and e-MTB riders using frames compatible with the SRAM Universal Derailleur Hanger (UDH) standard. It provides a robust, fully machined solution designed to protect your drivetrain by rotating backward during impacts, effectively preventing chain jams and derailleur damage. While it offers superior durability compared to standard stock hangers, users must ensure their frame specifically supports the UDH system before installation, as it is not backward compatible with non-UDH mounting interfaces.

FAQs
Is this hanger compatible with any bike?
No, it is only compatible with frames specifically designed for the SRAM Universal Derailleur Hanger (UDH) standard.
Does this work with e-MTBs?
Yes, the forged construction is robust enough to handle the increased torque and weight of e-MTB systems.
Do I need special tools to install this?
You need a standard hex key (usually 8mm) to remove the thru-axle and a smaller hex key for the hanger mounting screw.
Can I reuse the old mounting screw?
It is recommended to use the new mounting screw and washer provided with the Burgtec hanger to ensure perfect thread engagement and fit.
Why is the hanger supposed to rotate?
The rotation is a protective feature that allows the derailleur to move out of harm's way during a forward impact, preventing frame damage.
Troubleshooting
Shifting feels imprecise after installation
Verify that the hanger is seated perfectly flush against the frame dropout and that the mounting bolt is tightened to the recommended torque spec.
Hanger appears loose
Check the mounting bolt for wear or damage. Ensure the threads on the frame are clean and free of debris before reinstalling.

Setup, Compatibility & Care
Installation of the Burgtec UDH Hanger requires basic mechanical knowledge and a standard hex wrench. First, remove your existing thru-axle and derailleur. Unscrew the damaged hanger and clean the mounting surface on the frame to remove any grit or debris. Install the new Burgtec hanger using the included mounting screw and washer, ensuring the hanger is seated flush against the frame. Tighten to the manufacturer's specified torque setting—over-tightening can affect the rotation mechanism. Compatibility is limited strictly to frames designed for the SRAM UDH standard using M12 x 1.0 thru-axles. Regular care involves checking the bolt tightness periodically and ensuring the hanger is free of significant gouges or bends after a major impact.
