Product Information
Full details
The Cannondale Derailleur Hanger K33049 is an essential replacement component for owners of specific Cannondale bicycle models, such as the F-Si, Topstone, and Slate, who require a precision-engineered part to restore shifting performance. This hanger acts as a sacrificial piece designed to protect your frame from costly damage during an impact. While it is built to high standards, users should note that compatibility is frame-specific, and installing the wrong hanger can lead to permanent damage to your derailleur or frame dropout.

FAQs
Is this hanger compatible with all Cannondale bikes?
No, this is specifically designed for models using the DT M12x1 TA system, such as the F-Si, Topstone, and others listed.
Should I try to straighten a bent hanger?
While hanger alignment tools can sometimes straighten a hanger, it is generally recommended to replace a bent hanger, as the metal fatigue can make it prone to snapping in the future.
Does this part include mounting screws?
Please check your specific packaging, but generally, it is recommended to reuse your existing factory mounting hardware if in good condition.
How often should I check my hanger alignment?
It is good practice to check it after any significant impact, or at least every few months as part of routine maintenance.
Can I use this on a quick-release frame?
No, this hanger is designed for frames utilizing the DT M12x1 thru-axle system.
Troubleshooting
Gears are skipping after installing a new hanger
The new hanger may require minor adjustment or the derailleur limit screws may need to be reset to align with the new hanger position.
Hanger will not sit flush against the frame
Ensure no debris is trapped between the hanger and the frame dropout and check that the mounting screws are not cross-threaded.

Setup, Compatibility & Care
Before installing, ensure the bike is placed in a work stand for stability. Remove the thru-axle, detach the rear derailleur from the old hanger, and unscrew the hanger from the frame dropout. Carefully clean the dropout interface to remove any dirt or debris before attaching the new K33049 hanger. Ensure the mounting screws are tightened to the torque specifications provided by Cannondale. Compatibility covers various frames including: F-Si (2019), Synapse Carbon (2018-2019), SuperX, Slate (2016-2019), and Topstone (2019-2022). It is highly recommended to carry a spare hanger on long-distance gravel or mountain rides.
