Wheels Manufacturing Derailleur Hanger

This hanger is designed specifically for certain Cannondale frames. Before purchasing, verify your bike's model and year against the part number A239X/EBO, and check that your current hanger matches the 14.33mm hole spacing and 6.81mm plate spacing.

Derailleur hangers are designed to be the 'weak link' in your drivetrain. By using 6061 aluminum, this part is engineered to bend or break during an impact, effectively absorbing the force to prevent expensive, irreparable damage to your bike's frame.

Yes, this unit includes the two M3x10 socket head cap screws required for installation. You will only need a standard hex key to secure it to your rear dropout.

Wheels Manufacturing hangers are CNC machined to meet or exceed the specifications of original equipment. While they serve the same function, the precision machining often results in a tighter, more consistent fit than some mass-produced stock hangers.

While it is technically possible to straighten an aluminum hanger, we generally advise against it. Once the metal has been bent, its structural integrity is compromised, and it is much more likely to fail or snap under load, potentially damaging your derailleur.
