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.
