OPEN U.P./U.P.P.E.R. Rear Derailleur Hanger Info
The OPEN U.P./U.P.P.E.R. Rear Derailleur Hanger is the frame-specific replacement hanger designed to fit OPEN's U.P. and U.P.P.E.R. gravel framesets. Derailleur hangers are intentional weak points — they're designed to absorb impact and protect your derailleur and frame in the event of a crash or trail strike. Keeping a spare on hand is straightforward insurance for any gravel or adventure ride.
This hanger matches the precise geometry of the U.P. and U.P.P.E.R. dropout, ensuring correct derailleur alignment and reliable shifting performance. An exact fit matters here — a mismatched hanger affects indexing across the cassette and can cause persistent ghost shifting that no amount of cable tension adjustment will fix.
