Incorrect installation can cause inaccurate shifting, dropped chains, and even the rear wheel coming out while riding, which are serious safety incidents. We recommend installation and setup by a qualified technician using professional tools. Incorrect installation may also cause component damage or failure. This product follows the UDH (Universal Derailleur Hanger) direct mount standard. It is suitable for all UDH frames, such as newer UDH frames from Trek (Madone 8), Colnago (Y1RS), Cervelo (2026 S5) and Giant (2027 Propel), among other brands. The rear thru-axle thread must be M12 x 1.0mm. Not compatible with Factor One models. Please confirm your frame supports UDH and is compatible before purchasing or installing. Tools: Hex keys (UDH bolt: 10mm. Rear derailleur pivot bolt: 5mm) Before installing: Apply a suitable amount of grease to the threads of the supplied bolts (such as Shimano grease). Interface grease is not recommended. Recommended torque: UDH bolt: 25 Nm. Rear derailleur pivot bolt: 3-4 Nm. Tightening direction: UDH bolt: tighten counterclockwise. Rear derailleur pivot bolt: tighten clockwise. After installation, please check that the hanger is mounted square (perpendicular), re-check torque, test that there is no interference once the wheel is installed, and set up the shifting. If you have any questions or problems during first installation or use (for example the hanger angle shifts, or the rear derailleur angle is abnormal), stop immediately and contact us. Do not force the parts on or off, and do not continue using the product. Otherwise, it may cause inaccurate shifting, dropped chains, the chain being pulled into the wheel, or crashes. -------------------------- Links View the HotCheck Collection View other Direct Mount Hangers
