The Pilo D737 derailleur hanger is a superior quality replacement part specifically designed for Haibike Sduro, Xduro and e-Bikes frames equipped with a 12 mm thru-axle. CNC machined from aerospace-grade 6061-T651 aluminum with black anodized finish, this hanger offers superior durability and aesthetics compared to most OEM hangers. A true safety fuse between the derailleur and frame, it is designed to fail in case of impact to protect the rear derailleur and your bike frame — two components that are much more expensive to replace.

Technical Summary

This derailleur hanger matches the official Haibike reference DO-A91 (also known as part numbers #2501170090 and HW-DHG-012). It is perfectly suited for Haibike models produced between 2014 and 2020, including the Sduro Hardseven SL/RC/RX, Sduro Hardlife RC, Sduro Hardnine SL/RC/RX, Sduro Cross RC, Sduro Trekking RC, Xduro Cross RX/Pro, Xduro Trekking RX/Pro, Xduro Urban, Xduro Trekking RS, Xduro race/superrace and Xduro ALLMTN 8.0 ranges. The internal mounting with a single M5x10 bolt (included) ensures simple and quick installation. Weighing only 18 grams, this hanger does not add weight to your bike while guaranteeing optimal strength.

Technical Highlights

• CNC machined aerospace-grade 6061-T651 aluminum: Premium material offering an excellent balance between lightness, rigidity and impact resistance. CNC machining guarantees dimensional precision and finishing quality superior to cast hangers.

Installation and Recommendations

Installing this derailleur hanger requires only basic tools: an Allen key and ideally a torque wrench to respect the recommended torque. It is crucial to visually compare the hanger with your original part before purchase to guarantee perfect compatibility. In case of doubt, photograph your old hanger and the mounting point on the frame. Experienced cyclists recommend always having a spare hanger during MTB or e-bike outings, as this part can bend or break following a crash, contact with branches or rocks. Without a functional hanger, it becomes impossible to ride. Thanks to its precise design and manufacturing quality, the Pilo D737 hanger also improves gear shifting smoothness by ensuring optimal derailleur alignment.
