Specialized Mountain Bike Rear Derailleur Hanger

This hanger is specifically engineered for select 2018 and 2019 Specialized mountain bike models, including the Chisel, Epic, Levo, and Stumpjumper FSR. Because derailleur hangers are frame-specific, we strongly recommend verifying your bike's model year and checking your current hanger against the shape of this replacement before purchasing.

No, this specific hanger is designed exclusively for frames utilizing a thru-axle system. It will not fit frames equipped with standard quick-release dropouts.

While some hangers can be temporarily realigned, the metal often weakens or fatigues during the bending process, making it prone to snapping under load. Replacing the hanger ensures your derailleur is perfectly aligned with the cassette, which is essential for crisp, reliable shifting and preventing damage to your drivetrain.

Installing a derailleur hanger is a straightforward task that requires basic tools, typically just a hex key. Once the rear wheel and derailleur are removed, you simply unscrew the old hanger and bolt the new one into place, though you may need to perform a minor derailleur adjustment afterward to ensure perfect indexing.

It is a smart practice for mountain bikers to carry a spare hanger in their pack. Because the hanger is designed to be the 'weak link' that breaks to protect your expensive frame and derailleur during an impact, having a replacement on hand can save your ride if you take a spill on the trail.
