Cervelo Derailleur Hanger

This hanger is specifically engineered for Cervelo frames that utilize threaded thru-axle systems. Because Cervelo produces various frame designs, you should verify that your bike uses the DRH-WMN112 model number or check your bike's specific technical manual to ensure a precise match.

Yes, this is a complete replacement part that includes the essential 12mm mounting nut required for installation. You will not need to purchase additional mounting hardware separately.

Using a genuine Cervelo hanger ensures the exact geometry and material specifications required for your frame's alignment. Aftermarket alternatives may not offer the same tolerances, which can lead to poor shifting performance or potential damage to your derailleur and frame.

You should consider replacing your hanger if you notice inconsistent or 'ghost' shifting, difficulty indexing your gears, or if the hanger has sustained visible impact damage. Even a slight bend in the hanger can significantly degrade drivetrain performance, so it is often best to replace it if you suspect it has been compromised.

Installation is straightforward if you have basic mechanical skills and the correct tools, such as a hex wrench. However, because the hanger is critical for precise gear alignment, we recommend having a professional mechanic verify the derailleur indexing after installation to ensure everything is perfectly dialed in.
