Bontrager Road Derailleur Hanger

This hanger is designed specifically for road frames that utilize a 135mm quick-release axle system. Because derailleur hanger shapes vary significantly between bike models, we recommend comparing the visual shape of your current hanger against the product photos or checking your bike's manual to confirm the specific part number required.

No, this package includes the derailleur hanger only. You will need to reuse the existing bolt from your current hanger, so be sure to keep it safe during the removal process.

Yes, this is an original equipment replacement part from Bontrager. It is crafted from the same durable alloy as the hanger that originally came on your bike, ensuring consistent performance and structural integrity.

If you have basic mechanical aptitude and a set of hex keys, this is a straightforward installation. You simply unscrew the old hanger, align the new one on the rear drive side, and secure it with the single mounting bolt.

Derailleur hangers act as a sacrificial part designed to bend or break during an impact to protect your frame's more expensive dropouts. Because every frame manufacturer designs their dropouts differently, the hanger must be a precise, model-specific fit to ensure your derailleur aligns correctly for smooth shifting.
