OPEN U.P. / UPPER / ONE+ Derailleur Hanger

This hanger is specifically designed for the OPEN U.P., UPPER, and ONE+ gravel frame models. It is not a universal hanger for all bikes, so please verify your frame model before purchasing.

Yes, this hanger is compatible with both mechanical and electronic shifting systems from major manufacturers like Shimano, SRAM, and Campagnolo.

Absolutely. A bent or broken hanger is a common cause of ride-ending mechanical issues, and because they are frame-specific, you cannot simply borrow one from another rider on the trail. Keeping a spare in your saddlebag is a smart insurance policy.

Installation typically requires only standard hex keys to remove the mounting bolt and secure the new hanger in place. Ensure the mounting surface is clean and the bolt is tightened to the manufacturer's recommended torque specification to prevent shifting issues.

If you notice inconsistent shifting, ghost shifting, or if the derailleur cage looks misaligned with the cassette cogs, your hanger may be bent. A derailleur alignment gauge is the most accurate way to check, but visual inspection can often reveal obvious bends.
