2025 DT Rear Derailleur
A completely new design with the shift arm relocated to the front, preventing the arm end from contacting the cassette. Finished in DT’s signature two-tone color scheme.
The streamlined structure, combined with titanium bolts, reduces weight by 16 g compared to the previous version — approximately a 22% weight reduction.
