Marwi Union GH-258 derailleur hanger for Stevens Corratec

Stevens derailleur hanger: compatibility and features for Stevens and Corratec bike frames

The Stevens derailleur hanger is a small but essential component to ensure the smooth operation of your drivetrain. Mounted on the rear of the frame, this aluminum part connects the rear derailleur to the bike’s dropout. Although it may look insignificant, its role is crucial: in the event of an impact, it bends or breaks to protect both the derailleur and the rear triangle of the frame.

Compatibility with Stevens and Corratec frames

Stevens and Corratec bikes use derailleur hangers specifically designed for the geometry of their frames. Before replacing, it is vital to check the exact reference that matches your model. A Stevens derailleur hanger can be recognized by:

• Precision CNC machining in aluminum for a rigid fit,

• Mounting holes tailored to the frame design,

• Perfect alignment with the rear derailleur position.

This compatibility with certain Corratec models offers a practical solution for riders seeking a reliable spare part without compromising drivetrain alignment.

Technical features

• Material: CNC-machined aluminum, combining rigidity and light weight,

• Mounting: supplied with bolts for quick installation,

• Alignment: designed to maintain chain line accuracy and prevent shifting issues,

• Protection: acts as a fuse in case of crash or excessive stress.

Thanks to its design, the Stevens derailleur hanger absorbs shocks and prevents irreversible damage to the aluminum or carbon frame.

When should you replace your derailleur hanger?

A crash, a hard derailment, or a strong impact on the rear wheel can bend the hanger. Warning signs include:

• Difficult or inaccurate gear shifting,

• A visibly tilted derailleur,

• Cracks or deformation on the part.

In such cases, replacement is a safer option than attempting to realign it, which can weaken the component.

Conclusion

Choosing a Stevens derailleur hanger compatible with Corratec is essential to extend your bike’s lifespan and maintain smooth shifting. Discreet yet vital, this part connects the frame, the drivetrain, and the rear wheel. Keeping a spare derailleur hanger at hand is a smart precaution for any regular rider.
