The Super Record 12-Speed rear derailleur combines the highest quality materials for exceptional weight and unparalleled performance. The unidirectional carbon fiber front rocker arm reduces weight with an innovative shape that envelopes the cassette better thanks to 3D Embrace technology creating a double effect: allowing the chain to maintain optimum traction at all times thus increasing the speed power and precision of shifting.
Carbon fiber-reinforced construction to increase strength while keeping weight to a minimum
Optimized spring return for constant chain tension
Adjustment of the initial rear derailleur position
