Know before you buy
Derailleur hangers are frame-specific, not universal. You should compare the shape of your current hanger to the images of the DROPOUT-99 or check your bike manufacturer’s technical manual to confirm the exact model match.
A bent hanger misaligns the derailleur with your cassette, which leads to poor shifting, chain skipping, and potential damage to your drivetrain components. Replacing it restores the precise alignment needed for smooth gear changes.
Wheels Manufacturing hangers are machined from 6061 aluminum, which is designed to be the 'sacrificial' part of your frame. It is engineered to bend or break during an impact to protect your more expensive frame and derailleur from damage.
Generally, you will need a set of hex keys to remove the mounting bolts from your old hanger and secure the new one. Once installed, you may need to perform a minor derailleur adjustment to ensure your indexing is dialed in correctly.
Yes, keeping a spare hanger in your saddlebag is a smart practice for any cyclist. Because hangers are bike-specific and often difficult to find in local shops, having one on hand ensures a minor crash or trail-side mishap doesn't end your ride prematurely.
