Overview

Is the Wheels Manufacturing Derailleur Hanger 138 the right replacement for Eddy Merckx and Pinarello frames?

The Wheels Manufacturing Derailleur Hanger 138 is the correct replacement hanger for Eddy Merckx and Pinarello frames that require a two-fastener hanger. CNC machined from 6061 aluminum with a black anodized finish and made in the USA, it is stiffer than virtually any OEM hanger, which improves shifting precision and durability over the stock part. Because many bicycle manufacturers source hangers from a small number of suppliers and may make mid-year changes, Wheels Manufacturing recommends using the hanger photos to visually confirm fitment before installation.

This hanger requires two fasteners for mounting. Compatible frames and known fitments are listed in the Tech tab. A direct replacement for a bent or broken hanger, keeping your derailleur properly aligned and your drivetrain shifting cleanly.
