Overview
What is the Wheels Manufacturing Derailleur Hanger 25 built for?
The Wheels Manufacturing Derailleur Hanger 25 is the direct replacement for a bent or broken hanger on a wide range of frames that use the single-fastener Dropout 25 pattern, including many models from Trek, Scott, Pinarello, Orbea, Bianchi, BMC, and dozens more. CNC machined from 6061 aluminum with a black anodized finish and made in the USA, it is stiffer than virtually any OEM hanger, which keeps your derailleur properly aligned and sharpens shifting precision over the stock part. Because many bicycle brands source hangers from a small pool of suppliers and make running changes mid-year, Wheels Manufacturing recommends comparing your old hanger to the product photos to confirm fitment before installing.
This hanger attaches to the frame with a single M8 fastener and does not include mounting hardware, so reuse your existing bolt or add one to your order. The full list of compatible frames and model years is extensive and lives in the Tech tab. A derailleur hanger is designed to be the sacrificial part that bends or breaks before your frame does, so keeping a correct spare on hand means a quick fix instead of a ruined ride.

Get to know Wheels Manufacturing

There's more to Wheels Manufacturing than this one product. Our Wheels Manufacturing page has the full Wheels Manufacturing lineup we carry and more about the brand.
Visit the Wheels Manufacturing page →How do I know the Hanger 25 fits my bike?
Compare your old hanger to the product photos and check the Tech tab for the full list of compatible frames and model years. Many brands share the same hanger and some change it mid-year, so a visual match is the most reliable confirmation.
Does it include mounting hardware?
No. The Hanger 25 attaches with a single M8 chainring bolt, which is not included. Reuse the bolt from your old hanger or add one to your order.
Why choose Wheels Manufacturing over the OEM hanger?
Wheels Manufacturing hangers are CNC machined from 6061 aluminum and are stiffer than virtually any OEM hanger. A stiffer hanger holds derailleur alignment more consistently, which directly improves shifting precision and durability.
